While I personally think Police are necessary in a well functioning society, I will argue that Police unions are a large contributing factor behind the poor reputation Police have gotten lately. They have blocked much needed reforms, protected bad eggs, and are an argument for how a Union can force it's participants to support things they find morally repugnant.

I didn't ask If, I asked How, and I'd be surprised if you can find any examples.

You don't think unions negotiate work terms such as wages, working hours, conditions, etc.?

What are some of the reasons you think a labor union would form in the first place?

Have you ever heard of mandatory break requirements in certain industries? Think those ideas came from business owners?

"The National Labor Union was founded on August 20, 1866, in Baltimore, Maryland. It was the first attempt to create a national labor group in the United States and one of their first actions was the first national call for Congress to mandate an 8-hour work day."

You're responding to a post that gave you examples.

The mechanics are work contracts with a grievance process, if you're curious.
