Question

I filed a grievance at work, and since filing, have been blatantly retaliated against, including being threatened with a 10 day suspension, accusing me of not being at work, yet marking that I was, and I have solid documents proving I was at work. After 5 months of mediation being put off, (1 reason being we were 45 minutes into mediation, and the mediator wanted my main boss present because of him making very crude remarks about me to my union rep), I finally had my day of mediation. It didnt turn out like I expected. The mediator didnt look at my proof, only the attorneys went back and forth negotiating, and bottom line, they offered me an amount of money, that really is money owed to me because of working out of class for a year and a half (that was part of the grievance filed), and for me to leave. So, basically, I call it bribe money. Also, if I accept their deal, I have to drop the EEOC charges against them. Can they do this? Can an employer get away with retaliation?
