Many MANY years ago, when I worked in a grocery store, I was told that I would have to join the Retail Clerks Union. When I said I didn't want to join, I was told that I had no choice. For three years while in High School, I was a member of this union. And I'll have to admit, they were always right there. The first of every month, they were right there wanting their dues. What did they do for me?? NADA!! Not a single thing that was ever pointed out to me or expressed to me in any way. I have NEVER joined another union since.
