I don’t really have a strong opinion as to the right way to go on this, but from a purely legal-technical standpoint, is there a good reason for having the rule made at the state level rather than the local?
I mean, ordinarily I’d think that it tends to make sense to let things be legislated at a low level unless there’s a reason not to.
If a locality over-protects workers against heat then, okay, they suffer economically and maybe people and business head to the next town over. I’d think that that’d self-resolve without the state getting involved.
