Under the NLRA, you are never required to join a union. You may be required to pay union dues, and the union will still represent you in collective bargaining, but that doesn't make you a union member.
Google: "closed shop vs union shop" and you will see.
Basically you cannot have a business that only hires from a union, but you can have a business that requires you to join a union after being hired meaning the union cannot prevent you from joining them.
Or in other words in non-right-to-work states you can be forced to join a union.
