Oh, and to add, the union workers really get screwed by this.
Not only do they get paid a sub-minimum wage, a big portion of those sub-minimum wages get auto-debited directly into union coffers.
That’s why I left a company years ago when I suddenly got a card from the Teamsters. It was never explained to me that I’m supposed to have my wages deducted by this clowns. Instead of $14 per hour, I was left with around $12, and these pukes took away the other $2 /hr.
