We had a similar situation at our work. It is basically a public utility, transportation, that had always been contracted to non-profits, and was unionized. The contracts would usually run about 5 years and would be renewed at that time. I worked over 20 years while in that format. It was a happy place with decent pay, and generally a harmonious place to work. Then in 2010 the contract was given to an American for profit company. Very unusual as this was a Canadian utility operating in a large metropolitan center.
Pretty soon the place was crawling with their henchmen/women.
You know the saying, 'If it ain't broke..." Well they seemed to have the thinking, 'If it ain't broke, break it', as they proceeded to change everything, to the point that the place and job was almost unrecognizable. And the union just sat on their hands, seemed almost like they were paid off.
And rules were brought in, rules on top of rules. None of which actually made the job better or easier. It just seemed they wanted a situation where you could almost always be doing something wrong, so they could control you.
Cameras were brought in, (for safety of course), and GPS tracking. You could not go anywhere not being under their eye.
The strangest thing was how many of the employees went along with all of this, and in fact became part of the oppression. Even though we were supposed to be brothers and sisters in a union, some members revelled in their new found powers in this new "system". They could put the worst work on those that they didn't like, all with the blessing of the "system".
Since I have always had a rebellious nature, I was determined to not get caught in this trap. This strategy was complicated, so I won't go into too many details, but one thing I did find was, I was never bothered, never got called in, nothing was ever said to me. I remember talking to my coworkers, and commenting, that these guys were evil, yet they were, 'paper tigers'.
It was later that I was reading the Wave, and the parts about the petty tyrants, and my job immediately came to mind. Those principles have proven to be sound, and my experience seemed to confirm a lot of it.
I relate my story, not to give you advice on what to do in your situation, but just to relate a personal experience of a similar nature.
Good luck in your endeavours.
