I’ve been on a medical LOA since last year and tomorrow I go back to work and I keep thinking about how almost all my coworkers I knew are gone and processes have changed. Also that if I do something wrong I might injure myself again and be right back where I was a year ago (I have been cleared for full job duties by my doctor).
IMO the cutoff time is 9:30-10:00 depending on the person and the level of emergency, anything after and something important better be on fire.
