Do some state laws allow you to move hours from one pay period to the other without paying overtime? Here in WA State, over 40 hours in 1 week is mandatory 1.5x overtime pay. So 9-hour days would give you 5 hours of overtime pay one week, and short you 4 hours the other week. Many workers would be OK with that, and I guess government contractors probably just pass on the overtime to the taxpayers. Which is probably why you rarely see that work schedule (alternating 4x9 & 5x9) outside of government.
