Never been fired fired as I haven’t had that many jobs and jobs in academia usually don’t officially fire someone… the closest one I had was pretty wild though

I was taking a summer job in college on a clinical research project; part-time job, we got assigned working hours at the beginning of each week. I was one of the few students who did not have clearance for clinical/counseling work so I could only do lab work. My performance wasn’t the best and I couldn’t do anything besides processing samples, so after 2-3 weeks they stopped issuing me work schedules and I was “fired”… or at least that’s what I thought. Later it turned out the lead professor and the entire project got into a massive scandal (sexual harassment, bullying, etc… got on local news) that eventually got the professor fired (tenured btw so they can’t be officially fired, uni “convinced” them to leave), so every student worker was essentially laid off at that moment. Probably likely that the entire research team got something akin to a stop-work order earlier so that’s why I never got work assigned for those weeks…

So yeah, the answer was a combination of 1) I wasn’t that good of a worker and more importantly 2) the entire project we were on got into a scandal and was terminated
