I mean, unions famously are antagonistic to businesses regardless of worker treatment. I am in favor of unions usually but they often end up needing to justify their existence by continually pushing for more and more OR are pawns of the company anyway. Irrelevant to this post, but either way they are simply redistributing imperial wealth

police unions suck so bad because they are doing exactly what unions do: pushing for more rights and benefits for the works (who happen to be cops!)
