I had to go out on fmla several years ago. They only gave you 90 days officially, but since my boss liked me they waited till 120 to fire me. The other fun part is that short term disability only gave out a fraction of my income, AKA, not enough to pay rent & eat and stuff.
If your insurance has any sort of short term disability insurance, check it out. It’s pennies, but it’s better than no pennies.
