A lot has been said concerning right to work laws. What is the current status of such laws?

5 many states have passed the law.
I chose C because it won't be mandatory to be in a union since some workplaces force you to become a member by withdrawing money from your pay.

You're right. # 3 (C?) is the best answer.

Thank You!
