Mental Health and Work: What to Know and What to Do

Mental health conditions and workplace functioning have a relationship that runs in both directions. Mental health difficulties affect work — in ways that are specific, measurable, and often not fully recognized by the person experiencing them. And work circumstances — the demands, the environment, the relationships, the degree of control and meaning — significantly affect mental health.

Understanding both directions of this relationship matters for navigating it more effectively.

How Mental Health Conditions Affect Workplace Functioning

Depression and anxiety together affect a substantial portion of the working population at any given time. The NIMH describes depression as a condition that can cause severe symptoms affecting how a person feels, thinks and handles daily activities, including work. The effects on workplace functioning are real and specific: concentration difficulties, reduced processing speed, impaired decision-making, difficulty maintaining relationships with colleagues, reduced energy for sustained effort, and an increased likelihood of errors that compound both the work problems and the depression driving them.

Burnout — the state of chronic work-related stress that produces emotional exhaustion, cynicism, and reduced professional efficacy — occupies a complex clinical position. It is not a formal psychiatric diagnosis in the DSM-5, but it is a significant and common syndrome that frequently co-occurs with depression and anxiety, and that substantially affects workplace functioning in ways that deserve clinical attention.

How Work Circumstances Affect Mental Health

Several specific work circumstances are associated with increased risk of mental health difficulties. High-demand, low-control environments — where the demands are significant but the person has limited authority over how they are met — are among the most reliably stressful workplace arrangements. Social isolation in remote work, lack of meaning or recognition, and interpersonal conflict are also significant contributors.

Your Options When Mental Health Is Affecting Work

If mental health conditions are significantly affecting workplace functioning, several options are worth knowing about. The Family and Medical Leave Act (FMLA) provides eligible employees with up to 12 weeks of unpaid, job-protected leave per year for serious health conditions, including serious mental health conditions. The Americans with Disabilities Act (ADA) requires covered employers to provide reasonable accommodations for employees with disabilities, which can include modified schedules, reduced noise environments, or other adjustments that support effective functioning.

Seeking clinical support — through medication management or other treatment — does not require workplace disclosure. Getting effective treatment is often the most important step toward protecting workplace functioning, independently of what the workplace knows. The SAMHSA offers resources on accessing mental health support that can help with identifying appropriate care options.

The Most Important Step

When mental health is significantly affecting work — affecting the ability to meet basic job requirements, straining professional relationships, or producing errors that have consequences — the most direct path forward is addressing the mental health condition rather than trying harder to manage around it. Effective treatment for depression, anxiety, and burnout produces meaningful improvements in work functioning. Pushing through without treatment leaves the underlying condition unaddressed.

Frequently Asked Questions

Can I take leave from work for mental health reasons?

Yes — the Family and Medical Leave Act provides up to 12 weeks of unpaid, job-protected leave for serious health conditions including mental health conditions, for eligible employees at covered employers. Your employer may ask for a certification from a health care provider. Some states and employers have additional leave provisions. Consulting with HR is the appropriate starting point for understanding your specific eligibility.

Do I have to tell my employer I have a mental health condition?

No — you are generally not required to disclose a specific diagnosis to your employer. If you are requesting FMLA leave or ADA accommodation, your employer may require documentation that a serious health condition exists, but for FMLA leave they can’t insist on a diagnosis, and for an ADA accommodation a general description of your condition may be enough. Requesting ‘leave for a medical condition’ or ‘accommodation for a health condition’ is usually enough to start the conversation, though your employer may ask for documentation from your provider.

What are reasonable workplace accommodations for mental health?

Reasonable accommodations for mental health conditions might include modified work schedules (flexible hours or remote work to accommodate treatment appointments), quiet workspace options, modified expectations during a period of acute illness, leave for treatment, or adjustments to job duties that are specific exacerbating factors. What is reasonable depends on the condition, the workplace, and the individual’s needs.

How do I know if I am burned out or depressed?

Burnout is primarily tied to work-related depletion — the exhaustion, cynicism, and reduced efficacy tend to improve with adequate time off. Depression tends to be more pervasive — affecting motivation, pleasure, sleep, concentration, and mood across all areas of life, not just work. In practice, burnout and depression frequently co-occur, and many people who present with burnout are also depressed. A clinical evaluation can clarify the distinction.

If mental health has been affecting your work — your concentration, your energy, your ability to show up the way you want to — that is both a clinical concern and a practical one worth addressing directly.
