Some unions are in fact quite useful. For example, non-union electricians are often asked to do dangerous work and often have little to no recourse. Truck drivers also have unions and its one of the reasons that driving a truck is still a profession that can provide a good quality of life for its workers. Nobody complains about UPS, and every driver is a Teamster.

Public unions are somewhat problematic, I'll give you that. Police are the best example of overpowered unions. Police forces often have tremendous leverage against local governments which makes it hard to keep them in line. What's happened in NYC anytime minor reforms are tried is a disgrace.

I guess what I'm saying is that I don't have a problem with workers trying to unionize while recognizing that unions do have issues. Amazon warehouse workers are on the ground doing potentially dangerous work on fast moving floors with robots flying around. I think those people have a right to get paid a living wage given Amazon's profits.

Basically, if you treat your employees happy, they won't have any reason to attempt to unionize.
