I could understand the point of unions at one time (like right after the industrial revolution). I can also understand it in the situation of particular jobs. But honestly, I think the Union in most cases is just another company trying to earn their profit by pushing another company. Sometimes, they earn their profit by forcing people to join who don't want to join. I have problems with my boss, but I don't think I need a Union to make things better. I either need to work things out with him or find another job if the first isn't possible.
I will say I might be wishing for a Union once the new minimum wage laws kick in because I am probably not getting a raise just because the government required it for minimum wage workers. And even then, Democrats did that.
