Amazing how putting this on the front of your list just discredited your entire post instantly. Public labor unions are a particularly nasty parasite. The union in question, the Professional Air Traffic Controllers Union got overly greedy and demonstrated an epic level of hubris.
The results were not so good. Not only did they get burned permanently (the strikers weren't only fired, but banned permanently from employment with the Federal government), but they also set back all labor unions by swinging public opinion massively against labor unions in general.
