CB. Be sure to save any and all "write-ups", etc, even notices of verbal warnings,any communications from management, all of that stuff. It's all "ammunition".
And be careful what you put in writing. Less is more. You can also refuse to sign. You can note "I do not agree" on the document, and next to that the date and your initials.
GoingNorth, it happened to me too. Coworkers started a rumor that I was the big boss's mistress. When a permanent position became available, he would not consider me (even though I had retired from the same permanent position which I had done for 10 years entirely successfully.)
He said it was because I was old and would not be able to catch on to the computer. *The same computer I had been using those 10 years. I had been commended in writing for how I had caught on quicker than most peers.
When I challenged him he said it was because he could not support me because of perceptions that we were lovers. We were not.
Then? I was let go from the contract job.
I was rehired at 3 other prisons after that and did stellar work. One of those prisons had an especially complex and demanding program to navigate that required a week of training. I was already two years older still when I took that job. There were contract employees who were nearly 80.
Whatever the law, they can eventually get away with what they want to. I learned the only solution was to find another job. Leaving is the only option when they start laying on. That is what I think.
While we may win battles in the workplace, we will never win the war. The key is knowledge of rights and benefits. Like you guys have provided to CB here.
I will tell you another quick story, from when I was young. I was a waitress. There was a union. There was a specifically negotiated pay per shift. The boss was not abiding.
I went to the union.
I got let go, because the boss said I was reading a book on the job.
PS. I was. There was no business. The restaurant had been newly opened. After I set up all the tables and got everything else in order, I sat in the back watching the door. One time, I picked up a book. The bartender saw me and that was the basis for firing me.
I was young. It was a good lesson on how the game is played.
