The reality I have seen in every business I have worked in is that salaried employees are considered to work until the work is done. In only one of those companies did I end up in a salaried position, but that lasted all of about 7 months. But I saw so many stuff that were there when I arrived and still there when I left after a 10 hour overnight shift. Or worse arriving to work as I was leaving one morning and they were still there when I got back that night 15 hours later. It is not a healthy system but so many big retailers essentially rely this sort of forced overtime.
