I just found out that my manager has changed my 6/2010 employee review documents after she gave me the final, signed and dated by both of us. Now she has two completely different documents, one in my electronic scanned file and another (changed) copy that she is using to build a file against me. I received the worst review I have ever had in my career 1/2011. I am worried she will give me another bad review this coming 1/2012 review to finally get rid of me after 16 yrs with the system. I have other documentation in which she has changed my working hours based on month to month rules....??? Can anyone please advise me as to what I need to do to protect myself from further destruction by this manager?
