> Unfortunately, many companies are so greedy that they aren’t willing to compromise.

The same can be said about unions. Greed is just human nature, and there are humans on the company side and the union side.

Where do unions work well? Germany? What are they doing differently? Well, they don't have company level unions for one. They are per industry.
