Oh like how Wakefern lies about what time they finished...and says they gave you a door when you checked in but actually didn't call you for another hour or two.
There's no one size fits all solution, unfortunately, because not everyone is honest. Literally nobody trusts anybody.
Do you accept the bills with inaccurate times? That would change if that hourly pay was verified by the time on the bills.
As a Motor Carrier, where all responsibility is on me, I have had the signing of the bills become a major issue a couple of times in less than a year. Many brokers require times for detention, and many shippers/receivers want to refuse to allow this on the paperwork. I tend to get an attitude when my money is on the line, LOL.
