@irontoenail - The problem is that finding the balance is really difficult. There are places in the world right now where labor unions are being stamped out all together.
And then they get to put laws in place like the ones where you can be put on probation for six months on a low wage and with no job security and then fired before your employer has to start paying you benefits.
Or ones where there is a minimum wage that wouldn't support a hamster, leaving people desperate and turning to loans and credit cards to get by.
Sure, unions can overreach sometimes, but I still say they are better than the alternative.
