Ok, I was wrong on the Federal OT law, trucking is exempt from compliance with that law.
Rosty that does sound odd on the whole OT after 8 hours or 40 hours. Say they work 10 hours today but then only work 6 hours tomorrow and end up at 40 hours for the week. They want that 1 day of having 2 extra hours as being paid at the time and a half rate even though the average shows them with no OT worked.
