If enough people are fired for this reason and file complaints with DoL (US Dept of Labor), then surely the DoL will open a case against the company for unpaid wages. If I recall correctly, for a while, Amazon used to force staff to arrive early (before shifts) but did not pay them for it. DoL got involved and the rules changed. To be clear: It is difficult, but not impossible, to make labor practices change with the help of DoL. EDIT This part should have appeared first: I agree that your scenario is the most likely outcome, even if I think it is reprehensible!
