Can Unresolved Workplace Conflict Impact Employees Mental Health?

Author:  Michelle Phaneuf

In the current workplace, conflict is often seen as an inevitable part of team dynamics. Differences in opinions, personalities, and work styles can lead to disagreements that, if not resolved, can fester and grow. While conflict itself can be productive and lead to constructive outcomes, unresolved or unproductive conflict can negatively impact mental health and the workplace environment.

Conflict can arise from various sources, including miscommunication, differing values, competition for resources, or personal issues. When handled appropriately, conflict can foster creativity and innovation. However, when left unresolved, it can shift to a toxic environment that adversely affects employees’ mental health in some of the following ways;

  1. Increase Stress and Anxiety
    One of the most immediate impacts of unresolved conflict is increased stress and anxiety within and among employees. Tension can create a cloud of unease in the workplace, making it difficult to concentrate on tasks. Employees may find themselves ruminating over conflicts rather than focusing on their work, leading to a decrease in productivity. Research indicates that chronic stress, particularly in the workplace, can lead to severe mental health issues such as anxiety disorders and depression.
  2. Weaken Connections
    In a workplace where conflict remains unresolved, working relationships can become strained. Communication breakdowns occur, leading to misunderstandings and further conflict. This breakdown can create an environment of distrust, where employees feel reluctant to collaborate or share information.  As interpersonal relationships deteriorate, employees may isolate themselves, compounding feelings of loneliness and alienation.
  3. Generate Burnout
    Prolonged exposure to unresolved conflict can lead to burnout—a state of emotional, physical, and mental exhaustion. Employees who feel overwhelmed by ongoing conflict may struggle to maintain a work-life balance, often carrying the burden of workplace issues into their personal lives. Symptoms of burnout include chronic fatigue, irritability, and a sense of hopelessness.
  4. Decrease Job Satisfaction
    Unresolved conflict can erode job satisfaction over time. When employees feel trapped in a hostile work environment, their enthusiasm and commitment fades. This can lead to a cycle of disengagement, where the individual’s lack of motivation negatively impacts their performance and relationships with colleagues. The resulting discontent can create a ripple effect, impacting team morale and leading to higher turnover rates.

Given the potential impact of unresolved conflict on mental health, it’s crucial for both employees and employers to undertake strategies for early resolution such as the following;

  1. Keep Lines of Communication Open
    Encouraging open communication is crucial to addressing conflict early. Creating a culture where employees feel safe expressing their concerns can prevent small disagreements from escalating into larger issues. Regular check-ins and team meetings can provide opportunities for team members to voice concerns and share feedback.
  2. Increase Conflict Resolution Capacity
    Training in conflict resolution can equip employees with the skills needed to handle disagreements constructively. Workshops that focus on effective communication, active listening, and interest-based negotiation can empower individuals to address conflicts directly and collaboratively. This fosters a healthier work environment and enhances team unity.
  3. Further Support
    In some cases, involving a neutral third party can help facilitate resolution. Mediation allows individuals to express their viewpoints in a safe environment leading to mutual understanding and finding a resolution that meets both parties needs.
  4. Promote a Supportive and Psychologically Safe Culture
    Organizations strive to create a supportive workplace culture that values mental health. Those offering resources such as employee assistance programs, mental health days, and wellness initiatives can help their employees manage stress and build resilience. A supportive culture encourages employees to seek help when needed and fosters a sense of belonging.

Unresolved conflict in the workplace can have profound implications for mental health. From increased stress and decreased job satisfaction to strained relationships and burnout, the repercussions are far-reaching. However, by fostering open communication, providing conflict resolution training, and promoting a supportive workplace culture, organizations can mitigate these effects and create a psychologically safe environment for all employees.

Ultimately, addressing conflict proactively not only protects mental health but also enhances overall workplace morale and productivity. By focusing on conflict resolution strategies, companies can cultivate a workplace where individuals feel valued, heard, and empowered to create collaborative working relationships.

Over the past month, I spoke with three professionals who had recently been laid off. April , a former schoolmate, has over 20 years of experience and has held management roles at several organizations. Most recently, she led a team at a large oil and gas company, where she was instrumental in building out a new service area. Despite her accomplishments, a combination of economic challenges and a lack of connection with her new boss led to her dismissal. Having been involved in layoffs before, she understood the process, but when she called me, she admitted it was much harder to be on the receiving end. She felt overwhelmed by a mix of emotions: denial, anger, betrayal, and a deep sense of failure. Carol , once a mentee of mine, built a strong foundation in the finance sector, and her persistence earned her a team lead role at a competitive mid-sized firm. Therefore, her call caught me off guard; she was trying to make sense of being included in a round of layoffs that affected 12 others. Having just been promoted, she struggled to understand why she had been chosen. She reached out for support as she navigated both the practical and emotional aftermath. Joe had been a student in one of my classes. With a master’s degree and excellent communication skills, he established a respected career in the regional non-profit sector. We maintained contact and often crossed paths through work. Joe was frequently involved in launching new initiatives and was recognized by both his boss and the board for his contributions. However, when the sector faced financial strain, he and his manager were among the 15% let go. He contacted me a month after the layoff; he had taken time to process everything and was now reflecting on what direction to take next. These stories are not uncommon. In fact, with ongoing economic uncertainty, many professionals, regardless of their experience or performance, are facing unexpected career changes. While layoffs are always challenging, the way they are handled can significantly impact both the individuals affected and the organization. This highlights a critical challenge for organizations: how can companies manage necessary workforce changes with both strategic foresight and genuine care? In addition to engaging the Human Resources department early in the planning and execution process, many businesses are increasingly recognizing the value of utilizing third-party outplacement services. Outplacement services are employer-sponsored programs designed to support both the business and departing employees during layoffs or organizational restructuring. Typically included as part of a severance package, these services offer more than just logistical support; they help individuals navigate a difficult transition with confidence. Outplacement services can be customized based on the needs and budget of the employer. Offerings often include planning for workforce reductions in collaboration with the business, delivering termination messages, and providing one-on-one career transition coaching and emotional support to affected staff. More importantly, these services help affected employees regain focus by offering practical job search guidance, resume coaching, and career direction tailored to their experience and industry. For employers, outplacement services can deliver a clear return on investment. Companies that provide structured transition support often experience fewer legal disputes and benefit from a stronger employer brand, which can positively influence talent attraction and retention. Showing care during a difficult time speaks volumes to internal teams, affected employees, clients, and the broader market. Having worked closely with businesses and professionals throughout this process, I’ve witnessed the significant difference that experienced, neutral third-party support can make. In fact, a 2023 CBIZ report, referencing Bureau of Labor Statistics data, noted that individuals who received outplacement assistance secured new roles 40% faster than those who did not receive support (CBIZ, 2023). Just imagine if April had access to a coach experienced in private sector transitions, or if Carol had received immediate help with processing her layoff and planning her next steps; the positive impact would have been immediate. In today’s environment, outplacement isn’t merely a nice option; it is a strategic necessity. How will your organization ensure a respectful and supportive transition for its workforce? When selecting an outplacement partner, consider factors such as industry experience, the ability to customize services, the quality of career coaches, and the integration of digital tools for job seekers. Not all providers offer the same level of support or results, so thorough vetting is essential.
