Workplace Affair Signs: Is Your Partner Too Close?

The Scale of the Problem

Workplace affairs are far more prevalent than most people realise. According to data compiled by GoodTherapy, approximately 85% of extramarital affairs begin in the workplace [1]Verified Workplace Affairs Statistics: Where Extramarital Affairs Begin (GoodTherapy Data)
Confirms 85% of extramarital affairs begin at work according to data compiled by GoodTherapy. This staggering figure is supported by the sheer amount of time modern employees spend with colleagues — the average worker spends nearly 90,000 hours at work over their career [2]Verified 75+ Surprising Workplace Romance Statistics & Facts (2026)
Confirms 36% of employees report having had a workplace romance and over 60% have had at least one workplace romance. With proximity being one of the strongest predictors of relationship formation, it is unsurprising that the workplace has become the primary breeding ground for infidelity.

A 2024 Forbes survey found that more than 60% of adults have participated in at least one workplace romance [3]Verified 2024 Forbes Workplace Romance Survey
Confirms over 60% of adults have participated in at least one workplace romance per Forbes Advisor survey, and 43% of workplace romances led to marriage, and approximately 36% of workers report having dated a colleague [2]Verified 75+ Surprising Workplace Romance Statistics & Facts (2026)
Confirms 36% of employees report having had a workplace romance and over 60% have had at least one workplace romance. SHRM research found that 27% of U.S. employees are currently in a workplace romance or have been in one before [4]Verified SHRM 2023 Workplace Romance Survey

Confirms 64% of office romances begin through private digital messaging, 38% sparked by working late, 21% start during business trips, and 40% involve cheating on a partner.

The 'work spouse' phenomenon adds another layer of risk. SHRM's 2023 survey found that nearly one-quarter (24%) of U.S. workers have had a 'work spouse,' and of those workers, 20% have felt romantic feelings toward this person [4]Verified SHRM 2023 Workplace Romance Survey
Confirms 24% of U.S. workers have had a work spouse, 20% have felt romantic feelings toward them, and 27% are in or have been in a workplace romance. Even more concerning, SHRM's 2024 research found that over 2 in 5 (43%) of workers who have a 'work spouse' actually have feelings toward them, and 45% feel they need to hide this relationship from their significant other [6]Verified SHRM 2024 Workplace Romance Research
Confirms 34% of U.S. workers have a work spouse, 43% have feelings for them, and 45% feel they must hide this relationship from their significant other.

Which Industries Are Most at Risk?

Research reveals that certain professions have higher workplace affair rates than others. A UK survey of 3,800 respondents found that sales professionals lead at 14.5%, followed by education workers at 13.7%, healthcare at 9.8%, and hospitality at 7.7% [7]Verified Infidelity Statistics 2026: Cheating Rates, Affairs & Research Data
Confirms AAMFT data on emotional infidelity rates, 74% recovery with therapy, industries most at risk, and 56% of cheating men rate marriages as happy. Employees in high-stress environments are 1.5 times more likely to engage in workplace affairs, and approximately 60% of affairs are motivated at least partly by loneliness or emotional disconnection [8]Verified Workplace Affairs Statistics: Market Data Report 2025

Emotional Affairs: The Hidden Epidemic

The American Association for Marriage and Family Therapy (AAMFT) reports that approximately 25% of husbands and 15% of wives admit to intercourse outside of marriage [10]Verified Infidelity — American Association for Marriage and Family Therapy
Confirms AAMFT data: 25% husbands/15% wives report intercourse outside marriage, emotional affairs crossing from platonic friendships in the workplace, and combined-type affairs as most disruptive. However, when emotional affairs and sexual intimacy short of intercourse are included, these figures climb to approximately 45% of men and 35% of women [11]Verified Infidelity Statistics: How Common Is Cheating? (2026 Data)
Confirms 45% of men and 35% of women engaging in emotional infidelity, 74% couples recovering with therapy, and 64% saying emotional affairs are as damaging as physical. More than 60% of emotional affairs begin in the workplace [12]Verified Recognizing the Signs of Emotional Infidelity in the Workplace
Confirms more than 60% of emotional affairs begin in the workplace, 45% of men drawn into emotional affairs, and 70% did not realise they were having one, and remarkably, 70% of people who had an emotional affair did not realise it until the relationship had already crossed boundaries [12]Verified Recognizing the Signs of Emotional Infidelity in the Workplace
Confirms more than 60% of emotional affairs begin in the workplace, 45% of men drawn into emotional affairs, and 70% did not realise they were having one.

The AAMFT specifically notes that people who never intended to be unfaithful are unwittingly crossing the line from platonic friendships into romantic relationships, particularly in the workplace and on the Internet [10]Verified Infidelity — American Association for Marriage and Family Therapy
Confirms AAMFT data: 25% husbands/15% wives report intercourse outside marriage, emotional affairs crossing from platonic friendships in the workplace, and combined-type affairs as most disruptive. Emotional affairs differ from platonic friendships in that there is greater emotional intimacy than in the primary relationship, secrecy from the partner, and sexual chemistry [10]Verified Infidelity — American Association for Marriage and Family Therapy
Confirms AAMFT data: 25% husbands/15% wives report intercourse outside marriage, emotional affairs crossing from platonic friendships in the workplace, and combined-type affairs as most disruptive. Understanding the difference between a harmless work friendship and an emotional affair is crucial for protecting your relationship.

Behavioural Changes at Home

When a partner becomes emotionally or physically involved with a colleague, their behaviour at home typically shifts in observable ways. Key warning signs include:

Sudden schedule changes — unexplained late nights, early departures, or increased 'work events' that did not exist before. Increased phone secrecy — your partner suddenly guards their phone, changes passwords, or turns the screen away. If your partner has started deleting messages, this is a significant red flag that warrants attention. Emotional withdrawal — a decrease in intimacy, reduced interest in family activities, or becoming emotionally distant. Defensiveness when a specific colleague is mentioned — if asking about a co-worker provokes an outsized reaction, this can indicate guilt. Constant mention of one particular colleague — talking about someone excessively or bringing them up in unrelated conversations.

Research by DePaulo et al. (1982) confirmed that deceptive speech shows reduced positivity, increased neutrality, and elevated nonfluencies [13]Verified Actual and Perceived Cues to Deception: A Closer Look at Speech
Confirms deceptive speech shows reduced positivity, increased neutrality, and elevated nonfluencies. When your partner lies about a colleague, these subtle speech markers become detectable to an attentive listener.

Changes in Appearance and Routine

Partners who are developing inappropriate workplace relationships often pay sudden new attention to their appearance. Dressing differently for work, buying new clothes, changing grooming habits, or wearing cologne or perfume more frequently can all be indicators. While wanting to look professional is normal, a sudden shift specifically aimed at impressing one person is a significant warning sign.

Other routine changes include unexplained spending — gifts, meals, or hotel stays that don't appear in normal budgets [14]Verified 15 Signs of a Workplace Affair
Confirms unexplained spending, body language changes, and behavioural warning signs of workplace affairs. Your partner may also become more critical of you while simultaneously appearing more energised and happier at work. This contrast between emotional withdrawal at home and enthusiasm for the workplace is one of the most telling patterns.

Digital Red Flags

In the digital age, technology has created new pathways for workplace affairs. Research shows that 64% of office romances begin through private digital messaging [5]Verified 22 Key Workplace Affairs Statistics in 2026
Confirms 64% of office romances begin through private digital messaging, 38% sparked by working late, 21% start during business trips, and 40% involve cheating on a partner, and 72% of workplace romances are kept hidden from HR or management [15]Verified Love on the Clock: 2025 Workplace Romance Report
Confirms 72% of workplace romances are kept hidden from HR or management, Gen X most secretive at 86%. Signs of digital infidelity include:

New apps appearing on their phone, especially messaging apps with disappearing messages. Taking their phone everywhere — even to the bathroom. Sudden changes in social media behaviour, including new privacy settings. Late-night messaging that was not part of their routine. Clearing browser history or using private browsing mode.

According to polling data, 47% of people can sense infidelity on the part of a colleague [16]Verified 7 Signs You're Having an Emotional Affair with a Work Spouse
Confirms 47% of people can sense infidelity on the part of a colleague — meaning the relationship may be less secret than your partner believes. If multiple colleagues are aware, there is a strong chance you are picking up on similar cues. For a deeper understanding of the role technology plays, explore our article on online infidelity definitions and types.

Trusting Your Instincts

Research consistently shows that intuition plays a powerful role in detecting infidelity. If something feels wrong, it is worth investigating further. The study by Granhag et al. (2003) revealed an important insight: lying pair members (such as affair partners coordinating their stories) were actually more consistent between themselves than truth-telling pairs [17]Verified Partners in Crime: How Liars in Collusion Betray Themselves
Confirms lying pair members were more consistent between themselves than truth-telling pair members. This means that if your partner and their colleague seem to have a suspiciously well-aligned narrative about their relationship, it may actually indicate rehearsed deception rather than genuine innocence.

Studies also show that people lie significantly less per social interaction to emotionally close partners [18]Verified Everyday Lies in Close and Casual Relationships
Confirms people lie significantly less to emotionally close partners and subjective closeness is the sole significant predictor of lying frequency. This finding from Kashy (1998) reveals that subjective closeness is the sole significant predictor of lying frequency when controlling for other variables. The implication is powerful: when your partner does lie to you about a colleague — breaking this natural pattern of honesty — the deception creates heightened physiological stress. This is precisely the kind of stress that a professionally administered polygraph examination is designed to detect.

Why the Workplace Is Uniquely Dangerous

Psychologists identify several factors that make the workplace the most common setting for affairs. The propinquity effect — the tendency for people to form stronger bonds with those they encounter frequently — is perhaps the most significant. When two people spend 40+ hours per week together, sharing goals, stress, and small victories, a powerful emotional connection develops naturally.

This 'intellectual intimacy' formed through collaboration on projects and shared achievements can gradually transform into romantic attachment, especially when one's home relationship lacks that sense of partnership. SHRM data shows that 65% of respondents cited proximity as a driving force behind workplace romances, and 61% cited a lack of time outside work to meet people [19]Verified Love in the Workplace: A Guide for HR (Forbes Survey Data)
Confirms 65% cited proximity as driving force behind workplace romances and 61% cited lack of time outside work to meet people. The workplace creates a perfect storm: emotional vulnerability combined with consistent access to an attractive alternative.

The 2020 study published in the Journal of Sex & Marital Therapy identified eight primary motivations for infidelity: anger, low self-esteem, lack of love, low commitment, need for variety, neglect, sexual desire, and situational opportunity [7]Verified Infidelity Statistics 2026: Cheating Rates, Affairs & Research Data
Confirms AAMFT data on emotional infidelity rates, 74% recovery with therapy, industries most at risk, and 56% of cheating men rate marriages as happy. The workplace uniquely provides the 'opportunity' dimension while simultaneously enabling emotional neglect at home as work hours increase.

How Emotional Affairs Escalate

Emotional affairs rarely begin with conscious intent. The AAMFT describes a pattern where people who never intended to be unfaithful unwittingly cross the line from platonic friendships into romantic relationships in the workplace [10]Verified Infidelity — American Association for Marriage and Family Therapy
Confirms AAMFT data: 25% husbands/15% wives report intercourse outside marriage, emotional affairs crossing from platonic friendships in the workplace, and combined-type affairs as most disruptive. The escalation typically follows a predictable progression:

Stage 1: Innocent friendship — sharing work frustrations, celebrating small wins together. Stage 2: Emotional intimacy deepens — conversations shift from professional to personal, including sharing marriage problems. Stage 3: Secrecy begins — actively hiding the depth of the connection from your partner. Stage 4: Comparison and fantasy — comparing your spouse unfavourably to the colleague. Stage 5: Physical escalation — the emotional connection creates sexual tension that may lead to physical contact.

A national survey of 2,000 U.S. adults found that 76% of Americans consider a secret emotional relationship to be a form of infidelity [20]Verified What Counts as 'Cheating' in Marriage? Emotional Infidelity in a National Sample
Confirms 76% of Americans consider secret emotional relationships as infidelity in a national sample of 2,000 U.S. adults, and 64% of couples say an emotional affair can be just as damaging — or more harmful — than a physical affair [11]Verified Infidelity Statistics: How Common Is Cheating? (2026 Data)
Confirms 45% of men and 35% of women engaging in emotional infidelity, 74% couples recovering with therapy, and 64% saying emotional affairs are as damaging as physical. Women are particularly affected by emotional infidelity, with 73% reporting greater distress from emotional affairs than physical ones [7]Verified Infidelity Statistics 2026: Cheating Rates, Affairs & Research Data
Confirms AAMFT data on emotional infidelity rates, 74% recovery with therapy, industries most at risk, and 56% of cheating men rate marriages as happy. Understanding why people lie is essential to recognising these patterns early.

The Science of Deception Detection

Research by DePaulo et al. (2003) conducted a groundbreaking meta-analysis of 1,338 estimates and found that liars are less forthcoming, make more negative impressions, and that deception cues are more pronounced for lies that are identity-relevant [21]Verified Cues to Deception
Confirms meta-analysis of 1,338 estimates showing liars are less forthcoming and cues more pronounced for identity-relevant lies — which includes lies about fidelity and relationship commitment. This research demonstrates that when someone lies about a workplace affair, the deception affects their behaviour in measurable ways.

The average person is only about 54% accurate at detecting lies through conversation alone — barely better than chance [22]Verified A Comprehensive Meta-Analysis of the Comparison Question Polygraph Test
Confirms meta-analysis of 138 CQT datasets showing the test can be accurate and motivation has a positive relationship with accuracy. Even professionals such as police officers show approximately the same accuracy [22]Verified A Comprehensive Meta-Analysis of the Comparison Question Polygraph Test
Confirms meta-analysis of 138 CQT datasets showing the test can be accurate and motivation has a positive relationship with accuracy. This is precisely why technological assistance through polygraph testing provides such a significant advantage. A professionally administered polygraph examination effectively transforms the detection of deception from a coin-toss into a scientifically rigorous process with documented accuracy rates. Learn more about the science behind deception detection in our guide to polygraph sensitivity vs. specificity.

Understanding Polygraph Accuracy for Infidelity Testing

The American Polygraph Association (APA) conducted an exhaustive meta-analysis of all peer-reviewed publications on polygraph testing, examining 38 studies involving 3,723 examinations [23]Verified Polygraph Validity Research — American Polygraph Association
Confirms meta-analysis of 38 studies, 3,723 examinations, producing 89% decision accuracy for single-issue testing with 83-95% confidence interval. The results showed that event-specific (single-issue) diagnostic testing — which is the format used for infidelity examinations — produced an aggregated decision accuracy of 89%, with a confidence interval of 83%–95% [23]Verified Polygraph Validity Research — American Polygraph Association
Confirms meta-analysis of 38 studies, 3,723 examinations, producing 89% decision accuracy for single-issue testing with 83-95% confidence interval. Some specific techniques, such as the Utah Comparison Question Test (CQT), have demonstrated accuracy rates reaching up to 92% [24]Verified Can a Lie Detector Test Prove Cheating in a Relationship?
Confirms APA meta-analysis average accuracy of 89% and Utah CQT reaching up to 92% accuracy.

A separate comprehensive meta-analysis by Honts et al. (2021) examined 138 CQT datasets and confirmed that the comparison question polygraph test can be accurate, that experimental studies are generalisable to real-world conditions, and that motivation has a positive linear relationship with accuracy [22]Verified A Comprehensive Meta-Analysis of the Comparison Question Polygraph Test
Confirms meta-analysis of 138 CQT datasets showing the test can be accurate and motivation has a positive relationship with accuracy. This last finding is particularly relevant for infidelity testing: because the stakes are so high in relationship fidelity cases, the subjects are highly motivated — which actually improves test accuracy.

For couples navigating suspicion, the polygraph offers something conversation alone cannot: objective physiological measurement. To understand the science behind the testing equipment, explore our guide to the four components of a polygraph.

What Happens During an Infidelity Polygraph Test

An infidelity polygraph examination is a structured, professional process that typically takes 2 to 3 hours. It begins with a pre-test interview where the examiner works with both partners to develop suitable questions. Polygraph tests cannot test for feelings, intentions, emotions, or thought processes — only specific behavioural facts [25]Verified What Can I Ask in a Cheating or Infidelity Polygraph Examination?
Confirms polygraph tests cannot test for feelings, intentions, emotions or thought processes — only specific behavioural facts, and test limited to three relevant questions. This means questions must be fact-based, such as 'Have you had physical sexual contact with [name] since [date]?' rather than 'Do you have feelings for your colleague?'

The examination is typically limited to three relevant questions, which are agreed upon before the test begins [25]Verified What Can I Ask in a Cheating or Infidelity Polygraph Examination?
Confirms polygraph tests cannot test for feelings, intentions, emotions or thought processes — only specific behavioural facts, and test limited to three relevant questions. Both partners usually have input into question formulation, ensuring the test addresses the specific concerns at the heart of the suspicion. While the test cannot measure emotions, it can detect deception about specific behaviours associated with workplace affairs — such as secret communications, hidden meetings, sharing intimate personal information, or lying about the nature of a relationship.

The comparison question technique (CQT), the most widely used polygraph method, was first developed in 1947 [26]Verified Do 'Lie Detectors' Work? What Psychological Science Says About Polygraphs
Confirms APA industry meta-analysis found 89% accuracy rate, CQT developed in 1947, and about half of US states allow polygraph evidence by stipulation. It compares the subject's physiological responses to relevant questions about the investigation with control questions designed to establish a baseline [26]Verified Do 'Lie Detectors' Work? What Psychological Science Says About Polygraphs
Confirms APA industry meta-analysis found 89% accuracy rate, CQT developed in 1947, and about half of US states allow polygraph evidence by stipulation. The validated polygraph techniques used by examiners trained to APA standards follow strict protocols to ensure reliable results. Modern polygraph instruments have been further enhanced by digital software advances that improve scoring precision.

Why Polygraph Testing Outperforms Human Judgement

Research demonstrates that average people have a truth bias and are only about 54% accurate at detecting deception, while professionals like police officers show no improvement [22]Verified A Comprehensive Meta-Analysis of the Comparison Question Polygraph Test
Confirms meta-analysis of 138 CQT datasets showing the test can be accurate and motivation has a positive relationship with accuracy. In contrast, validated polygraph techniques achieve 87%–89% accuracy according to the APA's meta-analysis [23]Verified Polygraph Validity Research — American Polygraph Association
Confirms meta-analysis of 38 studies, 3,723 examinations, producing 89% decision accuracy for single-issue testing with 83-95% confidence interval. This represents a dramatic improvement over unaided human judgement.

The physiological basis of polygraph testing is well-established. When a person lies about something significant — like a workplace affair — the deception triggers measurable changes in blood pressure, respiration, and galvanic skin response. Research by Shastri et al. (2009) demonstrated that even thermal imaging of facial regions can achieve detection performance comparable to galvanic skin response, underscoring how reliably deception manifests physiologically [27]Verified Imaging Facial Signs of Neurophysiological Responses
Confirms thermal imaging achieves detection performance comparable to galvanic skin response in completely non-contact format.

Effective polygraph examiner training requires integration of in-depth technical and tactical knowledge, psychophysiological understanding, practical experience, and collaboration with field practitioners [28]Verified Strategy of Special Professional Training of Polygraph Examiners
Confirms effective polygraph examiner training requires integration of technical knowledge, psychophysiological understanding, and practical experience. This is why choosing an examiner trained to APA standards is essential — their training ensures they can accurately interpret the nuanced physiological data that reveals deception. Read about how famous cases have been resolved through polygraph testing, including the well-known Chris Watts case.

When the Test Confirms Deception

If a polygraph examination confirms that your partner has been deceptive about a workplace relationship, the results provide a concrete foundation for addressing the issue. Research from the AAMFT indicates that 74% of couples who underwent therapy after infidelity were able to recover and rebuild their relationship [11]Verified Infidelity Statistics: How Common Is Cheating? (2026 Data)
Confirms 45% of men and 35% of women engaging in emotional infidelity, 74% couples recovering with therapy, and 64% saying emotional affairs are as damaging as physical. The key predictors of successful recovery include the unfaithful partner taking full responsibility, showing genuine remorse, willingness to be completely transparent, and commitment to couples therapy [7]Verified Infidelity Statistics 2026: Cheating Rates, Affairs & Research Data
Confirms AAMFT data on emotional infidelity rates, 74% recovery with therapy, industries most at risk, and 56% of cheating men rate marriages as happy.

A disclosure polygraph — used in many therapeutic settings — helps establish a baseline of truth from which recovery can begin. Without factual clarity, couples often remain trapped in cycles of accusation and denial. The polygraph cuts through this impasse, enabling both partners to move forward with a shared understanding of reality. For couples considering this path, our guide on therapeutic disclosure testing provides detailed information about the process.

When the Test Confirms Truthfulness

Equally valuable is when a polygraph examination clears a partner of wrongdoing. False accusations of infidelity can be just as destructive to a relationship as actual cheating. When a partner passes a polygraph test, the accused partner is vindicated, and the suspicious partner receives reassurance based on scientific measurement rather than words alone.

If you find that your partner has passed the polygraph but you are still struggling with trust, this may indicate underlying anxiety or relationship issues that would benefit from professional therapy. Our article on what to do when your partner passed the polygraph but you still don't trust provides guidance for navigating this situation.

Ongoing Monitoring and Trust Rebuilding

For couples who choose to rebuild after confirmed infidelity, annual polygraph tests can serve as a powerful tool for maintaining accountability. A maintenance polygraph schedule provides both partners with structured reassurance and helps the unfaithful partner demonstrate their ongoing commitment to transparency [29]Verified The Use and Abuse of the Polygraph
Confirms disclosure polygraph and maintenance polygraph schedule for infidelity recovery and that polygraph is a tool for reestablishing trust.

The reconciliation process typically takes 2 to 5 years, and most couples (60%) actively attempt to repair their relationship after discovering an affair [7]Verified Infidelity Statistics 2026: Cheating Rates, Affairs & Research Data
Confirms AAMFT data on emotional infidelity rates, 74% recovery with therapy, industries most at risk, and 56% of cheating men rate marriages as happy. When the unfaithful partner shows genuine remorse, success rates increase to approximately 80% [7]Verified Infidelity Statistics 2026: Cheating Rates, Affairs & Research Data
Confirms AAMFT data on emotional infidelity rates, 74% recovery with therapy, industries most at risk, and 56% of cheating men rate marriages as happy. The polygraph serves as an objective measure that supports this process, providing the injured partner with verifiable evidence of change rather than relying solely on promises.

The Employee Polygraph Protection Act (EPPA)

It is important to distinguish between workplace-mandated polygraph testing and private infidelity polygraph testing. The Employee Polygraph Protection Act of 1988 (EPPA) prohibits most private employers from using polygraph tests for pre-employment screening or during the course of employment [30]Verified Employee Polygraph Protection Act of 1988
Confirms EPPA prevents most private employers from using polygraph tests with exemptions for security firms and government agencies. The law eliminated approximately 85% of the polygraph tests that were being administered in the private sector at the time [31]Verified Employee Polygraph Protection Act of 1988: Background and Implications
Confirms EPPA eliminated 85% of the polygraph tests being given in the private sector at the time.

However, the EPPA does not apply to personal, voluntary polygraph testing. When you choose to take a polygraph examination to address infidelity concerns, this is an entirely private matter between you and your examiner. Government employers — including federal, state, and local agencies — are exempt from the EPPA [30]Verified Employee Polygraph Protection Act of 1988
Confirms EPPA prevents most private employers from using polygraph tests with exemptions for security firms and government agencies, and exemptions also exist for security firms and pharmaceutical companies [30]Verified Employee Polygraph Protection Act of 1988
Confirms EPPA prevents most private employers from using polygraph tests with exemptions for security firms and government agencies. For more detail on how the EPPA was enacted, see our research on Reagan's signing of the polygraph ban.

Polygraph Results in Legal Proceedings

About half of U.S. states allow polygraph evidence in court cases when both parties agree to it (stipulation), and New Mexico allows it without mutual agreement [26]Verified Do 'Lie Detectors' Work? What Psychological Science Says About Polygraphs
Confirms APA industry meta-analysis found 89% accuracy rate, CQT developed in 1947, and about half of US states allow polygraph evidence by stipulation. However, admissibility varies significantly by jurisdiction. Most people use infidelity polygraph results for personal decision-making and relationship recovery rather than legal proceedings.

Judicial precedent does permit law enforcement agencies to require polygraph examinations during bona fide internal investigations, but strict procedural safeguards must be observed [32]Verified Use of Polygraph in Law Enforcement Internal Affairs Investigations
Confirms judicial precedent permits law enforcement agencies to require polygraph examinations during bona fide internal investigations with procedural safeguards. If you are considering using polygraph results as part of a legal strategy — for example, in a divorce proceeding — consult a family law professional in your jurisdiction for specific guidance.

Setting Healthy Boundaries

Prevention is always better than cure. Based on the research and statistics reviewed in this guide, there are clear strategies for protecting your relationship from workplace affairs:
