I have a friend with a union job (construction) and is overtime eligible. I would love to get paid for the hours I actually work and have a contract that details what I'm responsible for. I know tons of people who consistently work more hours than required and get a small bonus relative to the extra hours (9-11 hour days vs 7.5 required). Then the rest of us are seen as lacking potential because we 'only' work 7.5-8 hours. They are constantly adding additional responsibilities and expectations at an unrealistic rate without any real training.
When I was hired, they hired me for a Java developer position and then stuck me into Filenet work immediately. The company is notorious for hiring under a generic title and then placing you into some obscure stack like FileNet or Neoxam.
I know unions can have their downside, but having a contract and representation when dealing with violations of it would be awesome.
