I understand you've documented grounds for a grievance. Good; and good for you for proving they were wrong. They don't like it. Tough. Keep the ball in your court.

Also, consider this: it seems as though the days of working up through the ranks are over. No more is it What You Know - it's Who You Know. You really don't know who's connected to who, or who cells/texts who on weekends/before, during and after work/on vacation/even on sick days(!) I've figured it out after working on one job where a coworker was allowed to do anything she wanted-including cursing out a prominent person-because she kissed-up. No reprimand, no dismissal-and this was a public agency.

Sounds as though there's a vendetta against you. You'd think some people would have left middle-school behavior behind.

Meanwhile - maintain your professionalism. Every time you complete a project or assignment, check it and double ckeck, even with another coworker if possible. Document, and/or make a copy.

Next time they pick apart your work - ask why and ask for specifics. Whether or not they're willing to tell you - document, including full names/titles/dept./date/place of meeting/even their conduct, i.e. belligerent, arrogant, etc., the fact you asked (your exact question), and their response. Also ask them what makes them think you're not respecting their authority-and include that question, and their response in your documentation. What you're doing is standing up for your integrity. They're trying to tear you down.

Start a chain-of-command. I'd send a copy of every documentation to my supervisor anyway, as proof you're aware of what she's doing. If nothing's resolved within a timely manner, or after sending those copies you're still getting grief, next case is whoever's over your supervisor. Nothing's resolved? Next case is HR. Send them copies; meanwhile document if necessary. The chain-of-command proves you notified your supervisor, her supervisor, HR, and nothing was resolved. Lawyers and Courts love the chain-of-command route.

I say don't let them force you out; however continue looking for another job. Let's speculate. If, in the meantime, you're unfortunately fired either on some unfounded charge, or because you 'dared' to speak up, seek legal council with your documentation. You're being harassed = Hostile Environment. Illegal. Your documentation should prove as such.

Can't say it enough - keep documenting. Good luck.

Stay the course and continue to look for better opportunities. Sometimes you just have to smile internally at how inept some managers can be. As long as you are trying to the right thing and do, you have nothing to fear.

But keep an off-site file just in case.
