Is that really economical? At time-and-a-half?
I always thought overtime was the way to get around the fact that an 8 hour day doesn't divide very well into many tasks. So rather than hiring two people at 80 hours of pay to do ~50 hours of work (or even a 40 hr person and a 10hr person), it's cheaper to pay one person the equivalent of about 55 hours.
