I feel ambivalent about unions, but here's what I see.

Lots of people are criticising unions, because sometimes they are inefficient or corrupt.

Equally, I could write a rant about how employers are inefficient and corrupt.

So, my question is, what's the alternative to unionisation? Because currently, these arguments seem to say "let's get rid of the unions, and just let people be powerless and exploited."

Criticism is easy. Constructive criticism is something different.
