11 signs your toxic workplace is quietly harming your mental health and fueling burnout

A toxic workplace is becoming a major crisis nationwide, and new research reveals the severity of the problem.

A recent survey of more than 2,000 employees revealed that 75% have experienced a toxic work culture. In contrast, 87% said it directly harmed their mental health.

These numbers show how toxic work spreads quietly inside organizations and often leads to burnout, fear, and long-term emotional stress.

The hidden damage of a toxic workplace

The rise of toxic work is not just about bad manners or annoying coworkers. It creates deep cracks inside a company’s culture, according to Edstellar.

When toxic work becomes the norm, workers lose trust in their leaders, feel unsafe, and begin to disengage from their jobs.

Over time, this stress accumulates and develops into burnout. It affects mental health, lowers performance, and makes people leave their jobs much faster than usual.

Experts warn that these patterns should be treated as a serious threat. If left unaddressed, a toxic workplace can erode teamwork, disrupt communication, and compromise the organization’s future health.

How leadership fuels toxic work

Many problems begin with leadership. Ginny Clarke, Chief Executive Officer of Ginny Clarke, LLC, explained how toxic environments grow:

“Toxic behavior goes without consequences and fosters a workplace culture where you don’t feel safe, seen, or valued… Trust, respect, and transparency are non-existent, and it feels like everyone is on their own.”

Clarke explained that people often become disengaged and stressed in such environments. Based on her extensive experience with senior leaders, she said the problem usually stems from leadership—whether through acts of omission, doing nothing, or through actions that pit employees against one another, harming both the team and the organization.

Her message illustrates how harmful leadership behaviors can quickly spread to toxic work environments.

As a result, many employees seek help. Nearly 48% of employees turn to HR when dealing with toxic work environments, according to 2023 Workplace Harassment and Misconduct Insights.

However, HRD noted that 46% said they do not trust HR to solve these issues, and only 25% feel confident that HR will take real action.

This gap increases mental health struggles among employees who feel unsupported.

Why respect matters in a toxic workplace

A separate APA study found that 19% of employees say their workplace is “very” or “somewhat” toxic, and more than half said it hurt their mental health.

When disrespect becomes normal, it creates a cycle of fear, burnout, and emotional exhaustion.

As SHRM CEO Johnny C. Taylor Jr. stated, “When respect is absent, toxicity blooms and everyone loses.”

This simple truth shows how a lack of respect can turn a workplace into an unsafe environment where people no longer feel valued.

The high cost of toxic work on companies

Research from MIT Sloan found that a toxic work culture is 10 times more likely to lead to employee turnover than low pay.

This results in nearly $50 billion in annual turnover costs. Workers also share their toxic experiences online or with friends, which damages a company’s reputation and makes it harder to hire new people.

All of these consequences show how toxic workplace culture is more than a “people problem.” It also poses a significant financial threat.

11 signs you’re in a toxic work environment

A 2024 study have identified 11 clear signs that indicate when a workplace has become toxic. These behaviors often harm mental health and increase burnout.

1. Abusive supervision

Leaders often embarrass employees and impose impossible or unethical rules, such as unpaid overtime, which can lead to burnout.

2. Bullying

Aggressive actions that isolate, hurt, or offend employees or coworkers.

3. Unfair advantages

Some employees receive special treatment, while others lose opportunities.

4. Harassment

Unwanted sexual, racial, religious, or disability-based actions that create fear and harm mental health.

5. Incivility

Rude remarks, offensive jokes, or dishonest behavior, such as lying.

6. Interpersonal deviance

Gossiping, stealing, discrediting coworkers, or making subtle threats.

7. Interpersonal justice

Failing to treat people with dignity and respect, especially when they need support.

8. Ostracism

Ignoring someone or shutting them out makes it unsafe to speak up.

9. Social undermining

Putting someone down in meetings or spreading rumors that damage their confidence.

10. Workplace aggression

Actions meant to harm someone emotionally, verbally, or physically.

11. Workplace violence

Physical attacks or harsh verbal abuse that increase anxiety, depression, and deep mental health struggles.

Dr. Amy Sullivan, PsyD, reminds workers:

“A toxic work environment is a feeling and not necessarily a checklist. Pay attention to what your gut is sharing with you, as well as any physical responses you have before, during and after work.”

She added that toxic environments often arise when communication is confusing, biased, or inconsistent, and when leaders fail to address the needs of their team, Cleveland Clinic noted.

Why toxic workplace behavior spreads

Experts say toxic work grows in three significant areas:

• Leadership behaviors that destroy trust: Micromanagement, public shaming, favoritism, and leaders who refuse to take responsibility.
• Cultural norms that reward bad behavior: Gossip, blame, fear of making small mistakes, and environments where unhealthy behavior is ignored.
• Organizational gaps: Poor communication, lack of psychological safety, and leaders who do not follow the company’s values.

These patterns leave workers overwhelmed, stressed, and at risk of burnout.

How workers can protect their mental health

While companies must fix the root causes, workers can take steps to protect themselves:

• Seek therapy or support
• Set boundaries
• File a complaint with HR when safe
• Take mental health breaks
• Lean on supportive coworkers
• Focus on what you can personally control

Dr. Sullivan offers an important reminder: “Don’t settle for a toxic work environment. It’s not worth your physical or psychological health or your important relationships.”
