Have you ever researched the difference between the companies, the workers, how satisfied they are, how much they are paid, and why it was a quarter cheaper? You keep saying how the union affected you for your two projects, and how the union was the bad guys because you had to spend more time and money. Did you ever think that perhaps the workers at the union company could have been secure in their jobs, happy with their work/life balance and that the workers at the other company could be beaten down, pushed too hard, paid too little?
In any case, your few experiences could be caused by a lot of stuff, perhaps not even the union! I don't know, without more research. Your particular story is from your perspective only, and doesn't even delve into any other reasons this could have happened, like local noise ordnances or something.
This is my point: you don't care about the human cost of your entrepreneurial enterprises, and that is in my opinion the reason that America seems to be infighting and "going downhill" as they say. Greed, an uncaring attitude about others, and narcissistic "me me me" behavior is the problem, not a few workers trying to get a bigger cut. Unions aren't the enemy, those who would attempt to take advantage of workers are. America is only strong if we're all strong, not just a few tenths of a percent at the top.
I am not replying any more to this thread, all I have to say was said here.
