I feel like your HR is not doing you any favors. We are trained to do a minimum of 3 but we always give people at least 4.
I feel like most people would rather work one 6 hour shifts than two three hour shifts.
But if we're getting a truck everyday I need to be there everyday rather than them give me extra hours on one day. I half understand the process of it- but less than four hours isn't enough to push all my flow stuff.
