I don't know if this counts but like I said the center manager said he would appreciate it if I withdrew and he would have this supervisor be more respectful and would also appreciate me "performing" better and goes on about numbers and bs I don't care about. It's like they can't be nice without it being a backhanded comment you know? like I'm the wanting some dignity in this place. I appreciate that it's really not asking for much to be treated humanMaybe you made your point.
Time will tell if the Article 37 behavior stops.
IMO You are right to be suspicious of all UPS management.
When I was Steward I never withdrew a grievance without getting something specific in return.
Even if it was simply a documented commitment to change.
I do hope your hostile work environment improves.
You deserve it because we all deserve it.
