Right to work states are right to work for less states...just google income & poverty stats in those states. unions gave us the worker rights we have today: 40 hour work week, child labor laws, overtime pay, sick days, vaca, holidays, minimum wage, etc. Union membership's decline graph parallels the decline in wages graph over the last 30 years. Those are the facts.
