This has been rehearsed here before, as has an actors right to their roles such that he would have to be terminated with all of the procedures for doing so under the production contract."
Let me say first- I agree generally with another poster that the folks who were in a show when the shutdown happened should be allowed to continue when it reopens, I do wonder whether its required legally, though. The casts were all under contracts, presumably with start and end dates. At this point, I'm sure the end dates have long passed. Therefore, the contract has expired (unless it was by number of performances), so technically the productions could do what they want. Now, that doesn't mean that they shouldn't just re-hire everyone who wants back (plus it makes more sense to- at least those folks know the show, which makes getting the show back up and running easier). However, if someone was on their way to getting fired, or had a very short time left on their contract and was not going to get an extension, that may be a different story. Not that the actors would do this, but its also a different story if one of the actors held out for a significant pay bump (unless one was coming anyway before the shutdown).
One other thought- if the contracts are set up such that the producers are required to bring a cast member back, the case members would likely be required to return as well. Sure, most if not all of them would want to, but some may have found something else during the shutdown and for whatever reason (money, stability, career advancement) want to stay with the new role (or whatever).
Given a number of productions still do not have case lists on their website, my guess is at least a few are still working on either getting everyone signed up or are looking for some new people for whatever reason (including some folks no longer being available).
Again, the producers should, in 99% of the cases, rehire everyone. However, they are probably not legally required to, just as the cast members are required to come back.
