I work preload and averaged about 8.5 hours on Sunday/Mondays - starting as early as 10 pm Sunday evenings.
During the remainder of of the week, I averaged about 6.5 hours per day. I could have picked up more hours, but there were others who appreciated the overtime more than I do.
I'm sort of kicking my self in the butt right now, though, because the extra hours would have padded my worker's comp checks.
