Whether you can use sick days for mental health in the US depends on your employer’s policy and your state’s paid sick leave law — but the answer is increasingly yes. Most paid sick leave laws explicitly cover mental health, and many employers have updated their policies to recognise mental health as a valid reason for sick leave.
Key Takeaways
- State paid sick leave laws in California, Oregon, Washington, New York, and others cover mental health — a mental illness is a “illness” under those laws.
- Company policies may explicitly include or exclude mental health days — check your employee handbook.
- If your employer has a combined PTO bank (not separating sick and vacation), you can use it for any purpose without needing to specify the reason.
- FMLA covers serious mental health conditions requiring ongoing treatment — depression, anxiety, PTSD may qualify.
- The Americans with Disabilities Act may require accommodation for mental health conditions, which could include intermittent leave.
Do State Sick Leave Laws Cover Mental Health?
Most state paid sick leave laws define “illness” broadly. Here is how key states handle it:
- California — the Healthy Workplaces, Healthy Families Act covers “mental or physical illness, injury, or medical condition.” Mental health is included.
- Oregon — paid sick leave explicitly covers mental illness. A “sick” day can be for mental health.
- Washington — the paid sick leave law covers “mental or physical illness, injury, or health condition.”
- New York — the City’s earned sick time law covers “mental or physical illness, injury, or medical condition.”
- Massachusetts — earned sick time covers “physical or mental illness.”
- Illinois — the paid leave law covers “any reason” since Illinois moved to a universal paid leave model in 2024.
If you live in a state with a paid sick leave law, you can generally use your sick time for mental health in the same way you would for physical health.
What If Your Company Policy Is Unclear?
If your company policy says “sick leave must be for illness or injury” without defining whether mental health qualifies:
- Ask HR for clarification — many companies have updated policies but not communicated them
- If the policy does not explicitly exclude mental health, it is generally considered included
- Some employers require documentation — a note from a therapist or counsellor should be accepted
- For a mental health day (a single day of rest), many employers now accept it as a valid use of sick time
The trend since the pandemic is strongly towards including mental health. By 2026, most major employers and progressive small businesses explicitly cover mental health days.
Using FMLA for Mental Health
For serious mental health conditions, the Family and Medical Leave Act may apply. A serious mental health condition requiring inpatient treatment or continuing treatment by a healthcare provider may qualify for FMLA. Examples include:
- Major depressive disorder requiring medication adjustments and therapy
- Anxiety disorder requiring regular psychiatric treatment
- PTSD requiring ongoing care
- Bipolar disorder requiring mood stabilisation
- Eating disorders requiring specialised treatment
To qualify, you typically need documentation from a healthcare provider confirming the condition and the need for leave.
FAQ
Do I need to tell my employer why I’m taking a mental health day?
If you are using a sick day, you generally do not need to specify the nature of your illness — whether physical or mental. You are entitled to privacy about your health condition. Simply saying “I need to use a sick day” should be sufficient.
What if my employer demands a doctor’s note for a mental health day?
In states that restrict doctor’s note requirements (California, Oregon, Washington apply these rules to mental health too), they cannot require a note for short absences. In other states, a therapist or counsellor’s note should be accepted if documentation is required.
Can my employer deny my sick day for being “stressed”?
If paid sick leave is available for mental health in your state, your employer cannot deny the day because they do not believe stress is a valid illness. The decision of whether you are fit for work is yours to make in good faith.
What counts as a serious mental health condition for FMLA?
A condition requiring inpatient care (overnight hospitalisation), or continuing treatment by a healthcare provider — typically meaning two or more visits within 30 days. Acute stress without ongoing treatment does not qualify.
Are mental health days the same as “wellness days”?
Some employers now provide dedicated wellness days or mental health days as a separate entitlement from sick leave. These are above and beyond statutory requirements. If your employer offers them, you do not need to use your sick days for mental health at all.
