In my work area I have two overzealous sups who are constantly harrassing new hires. They are always looking for ways to threaten them with writeups, warning letters, etc.(although they leave more experienced employees alone for the most part), and are always lying to them telling them they have to sign practically everything they put in front of them. These are senority employees with maybe 6 months to a year of experience. I do my best to set them straight with what I do know, but there are huge descrepancies among even veteran employees it seems as to what we are required to sign besides our paychecks. Can someone set the record straight as to what we are required to sign versus whats optional without putting our jobs in jeopardy?
