only supposed to train and supervise, officially
you could try grieving a supervisor clearing an egress, but since it's an immediate safety issue you'll probably lose
being a preload supe is easily the worst PT supe job in UPS. between the FT's who scream about numbers and jack*** hourlies who blame you for what is WAY above your head, it is a really no-win situation that you just have to try to make the best of.
as far as UPS is concerned though, it's better to just work, get your people out sooner, and eat the grievances
they're on different reports so most supes don't care lol
