Original poster, yes it sucks but when they’re all against you… I’d be ready to get fired buddy!
I’ve been fired a couple of times in different jobs and every time I saw it coming miles away. I’d take all the advice in this thread, definitely get yourself an avenue to sue for improper dismissal (if no customer has ever had a problem and you haven’t broken any rules then you shouldn’t get fired) and start looking for something better.
Life’s too short to TRY to be at a place where you don’t fit in.
