Unions seem like a good solution on the surface, but it seems like many unions quickly degrade into organizations focused more on self-preservation and expansion than looking after the interests and well-being of their members.

It seems like it also gets ugly, with unions not only striking for better pay and benefits, but also protesting and demeaning individuals and companies who aren't using union labor or putting in policies that work must be done by union workers that could easily be done by others at a much cheaper rate or with much less effort. ("Let's get a union electrician in here to run this extension cord")

I'd be more in favor of unions if it were done completely on a volunteer and donation basis, instead of with mandatory dues, paid leadership and policies that demonize those who choose not to join the union or people that choose not to use union labor.

An alternate solution would be to put laws in place that stops employers from preventing their employees from voicing concerns about policies and treatment publicly. (while still allowing employers to protect intellectual property rights) I'd argue that all these stories about the treatment of former Amazon employees will have more of an effect on Amazon, its hiring efforts and its policies than having a union threatening a strike would.
