If it woulnd’t break some kind of fair labor standard, I would withhold these peoples’ pay checks until they show up as ordered.
We little people can be terminated for insubordination or incompetence. Let it happen to the “gentry” too.
I rather with this theory when it might be justified. A cut in the paycheck if one is justified, should accomplish in most cases one of two things; either an attitude adjustment or a resignation.
