Yes, Alan, it is coercion. If stores hadn't been open on Thanksgiving, people would have waited for Black Friday to spend their money. You seem to know enough about business to know (as I do) that working over a holiday on a non-emergency basis is rarely considered an "opportunity"; it is pretty much a requirement even if the employer offers it as "voluntary".

I say this as someone who has been on coverage for or actively worked through many a holiday and didn't get paid a dime extra for it. My bonus was "getting to keep my job". I know how it works.

I also know that most employers would just as soon suck you dry and kick you to the curb. What the hell, maybe employers should just tell people the new work week is 120 hours a week for the same pay. If they don't like it, hey, they can just walk, right?
