I know what you mean. We lost the largest employer we had in our little town because the union kept striking. The employer tried to be fair. The last time they entered into negotiations, the union threatened to strike if all of their demands were not met. The management told them that the owners would close down the business and sell out if that happened. The union did not believe them. They went on strike anyway. Guess what? The business closed its doors, was shut down, and went on the selling block. All those people lost their jobs.
It has finally, after several years, been purchased by a German company. They have only hired back a skeleton crew, the best of the best. It will be years before they will have enough business to hire as many people as had formerly worked there.
Kudos to that company. More should do the same. What I object to is closed shop unions. It is highly unconstitutional to force association. Freedom of Association works both ways.
