Right now, there are people who are actively fighting against the nomination of potential labor-secretary Hilda Solis because she is pro-union.
Why do people hate unions?
Do you have the right to quit your job when you want? I'm pretty sure most of us would say yes.
Do a group of people have the right to all quit their job at once? Again, most people would say yes.
Do a group of people have the right to say "Unless we get X, Y, Z we're all going to quit, oh and Bob here who's a lawyer is going to work on the contracts"? Again, most people would say yes.
Does their employer have the right to say "Screw you all, you're all fired! I'll take the financial risk because I'm not giving in to your demands."? I'm pretty sure people would say "yes".
Sure - unions can ask for to much. Employers can demand to much. You know what that's called?
People negotiating for their contracts to maximize their income while companies negotiate to give them the least? Last time I checked, that's the law of supply and demand at work. If a company makes a stupid ass contract that costs them money (as some would argue GM did with the unions), that's their own fault. They should have negotiated better. If a union doesn't get everything they want - again, they should have negotiated better. If the company up and moves overseas, well, again, that's capitalism - but then again, the company better be willing to pay the other prices (language barrier, etc, etc, etc).
So again, what's wrong with people banding together in having their say? I just don't get the "OMG UNIONS EVIL" mantra I see from some corners.
