Do I need to give my employer any written proof (documentation) if I take time off?
The law doesn’t specifically say that you need to give documentation to your employer, especially if you told your employer ahead of time that you need time off from work.1 However, it seems reasonable that if an employee asks for time off due to this law, the employer might ask for proof that the time off is for a qualifying reason under this law.
If you take time off without telling your employer ahead of time, providing documentation to explain your absence becomes more important. Again, the law doesn’t specifically say that an employee must provide documentation, but the law does say that if an employee provides documentation, the employer cannot punish or fire the employee.2
To see what types of documents are acceptable to give to your employer, go to What documentation is needed to request a reasonable accommodation?2
