So I work overnight at an ihop where i have called in a few times sick, without any forms. I came into work last night and received two different write ups for two different occasions where I called in sick and have yet to produce any form of paperwork from a doctor or whomever. The two manager's were disputing whether I was told about this, and whether or not they knew, I said I was informed once, however I would like to speak with the manager who wrote me up before I sign anything, they said they would have to fire me on the spot if I didn't sign these write ups then and there.
Anyway, I signed them, promising to bring in medical paperwork for one of the occasions, which I have, but the other one was a simple stomach flu and I didn't need a doctor.
Am I entitled to any legal recourse given that I know I should not have had my job threatened over signing this paperwork, as it can be filed unsigned?
