It varies wildly by manager. When I was at Amazon, one of my coworkers had a serious mental and physical crisis. Our manager went out of his way to support them, granting them unlimited leave, accepting them back on a part time / temporary basis whenever they felt up for it, etc. To make this work, though, I'm pretty sure the manager and probably his manager went around the system and basically didn't report the absences, because corporate policy almost certainly would've been to fire them. It effectively cost that manager an invaluable headcount spot, and it went on for over a year. I generally hated working for Amazon, but I loved that particular manager and would happily work for him again anytime.
