I dont' get any of those things but have no desire to join a union. I would never anticpate them getting me much more salary, and certainly don't want another monthly bill to pay.
I vote with the GDI (for those may not know, the "I" stands for Individual) folks. Being an "at will" employee provides a motivation to be "my" best. When I can't produce any longer, I expect to be replaced and I'm okay with that...if I couldn't produce for the company I'd fire myself! Success (in the eye of the beholder) is out there for any one willing to pursue it. Unions are great for some folks and some work groups but not me...can't see paying someone to do something I can do for myself and for sure not on anyone's back.
