If you could discover an email where an executive admitted their RTO strategy was a layoff then maybe, in some jurisdictions. But it's hard to prove, most of the time they could just say their motivation was "culture" or similarly vague and unfalsifiable like that.

I think it depends how far you are. There are laws covering you against forced relocation, treating it essentially as a layoff if it’s >50 miles (not sure exact numbers, and it may be state specific)
