"Don't kill the job" was a popular expression.
Soon as I left that job and I was able to negotiate and work for myself, my income and opportunities broadened considerably.
I worked with electricians (I was HVAC) who bragged about jobs where they carried conduit back and forth to "look busy" until break time. Then resumed "looking busy" so no one would get laid off on an over manned job site.
I use to be a non-union concrete contractor. Occasionally, I would make a sales call to someone who needed some work done who was a member of a union. A lot of times you can tell from bumper stickers on their vehicles. This would be for their own home. Sometime, when I was in a smartass mood, I would ask if they are getting bids from union companies. They would look at me as if I had two heads. That would be way too expensive!
