what was the result of the decision in Janus v. AFSCME : (what is right answer from the following)

1) Labor unions in right to work states could no longer force workers to pay union dues.

2) Labor unions in non-right to work states could no longer force workers to pay union dues.

3) Not all workers can automatically deemed "employees".

4) If one works for an employer more than 50% of the workable hours on a permanent basis, he or she can not be deemed "an independent contactor".
