As someone who came from an entire career with no unions to my first job now with one, this is correct. The union is who represents you. You no longer have the power to individually bargain for better wages or what be it. Being in the union has proved to me, they really don't do much unless they want to. My experience doesnt account for being picked over someone with more seniority than me, I could be better, more qualified and more deserving of a raise or promotion, but if someone else with lesser credentials has been there longer, they get it. I accept that and move on with my day.
