I am an employee of a large corporation and was recently part of a reorganization. The position I fell into was not the job I was initially hired for and my training and advancement opportunities became severely limited immediately. After only 2 months in the position, I went to HR because I felt I was being treated differently than anyone else. HR spoke with my manager and that treatment stopped. Now I was told someone heard me swear (not at anybody, just in context) while I was working. Management was quick to document it and the date along with other things. I was told to sign this write up that contained things I disagreed with so I declined to sign. They told me they could review me for termination, for a first offense. I've been suspended and they are now claiming things (that were undocumented or unknown to me) from a time other than the date on the letter. They have been doing an investigation for 10 days and I am not allowed to know much about it. What can I do? I believe that this may be a form of retaliation from the complaint I lodged against management.
