If you’re considering a mental health leave, you’re likely already overwhelmed, and worried about what could happen at work.

Many employees hesitate because they’re afraid:

  • their employer will question them
  • their job won’t be protected
  • they’ll be treated differently when they return

A poorly handled request can create problems. A properly handled one can protect your job and your rights.
