You Got Me Twisted!
If a manager or employer, as a whole, is targeting you, there aren't many stones that they are willing to leave unturned in an effort to prove that you are at fault for whatever treatment you have received and to justify that treatment as a reasonable and appropriate response to what you've allegedly done.
The best thing you can do for yourself is to pause before you answer any questions and think carefully about what you say, if you participate in any meetings to discuss what's going on. You also have to be careful with what you say to coworkers because you never know who might take advantage of your situation.
Your words can be manipulated into all sorts of meanings, including possibly turning your words into threats.
I have a current coworker who says that an associate threatened her with physical violence. The associate said, "I got something for you. I'm going to talk to ____ (store manager)." The associate he said this to repeated everything except that he meant he was going to report her. Luckily, another coworker heard the exchange and could attest to the fact that he meant he was going to management, not that he was going to hit her, beat her down, call his sister to wait for her after work, etc. as was being alleged.
You just never know what real words will be twisted or better yet which words will be totally made up.
But, as I always say, don't give anyone ammunition to use against you. Stay away from profanity, don't make any statements that can be construed as a possible threat, don't threaten a lawsuit or outside intervention (just do it, if you're going to do it), don't talk about job searches, don't talk about the details of what's going on with your abuse at work because the walls talk, and just watch your back.
There are people who will help sabatoge you and who will help you out the door, if they feel there's something they can gain.
Think carefully about what you say and try to keep your emotions in check because that is when you are more likely to make a comment that you'll regret later!
