The latter is essentially a term of art, the former is not. Using the former is imprecise and confusing.
> Realistically, it's best described as "mutual right to terminate employment without cause" or just "right to terminate".
That is a completely different concept called at-will employment. RTW is about union shops (not to be confused with closed shops, which have been illegal in the US since Taft-Hartley)
It's better to just allow people to name their own movement, otherwise, you end up endlessly fighting about names (i.e. are people 'pro-life' or 'anti-choice' and 'pro-murder'/'anti-life' and 'pro-choice').
Right to work laws do not in any way provide a right to work.
Especially since RTW legislation is not about closed shops (which are illegal at the federal level), so these were jobs you could always get.
What?
Goes to show... something, I guess.
