The rule is no more than 80 hours per week averaged over a 4 week period, so some weeks you pull more, others less. Not every block requires 80 hours/week. Gene

The rule is no more than 80 hours per week averaged over a 4 week period, so some weeks you pull more, others less. Not every block requires 80 hours/week. Generally though, 24h shifts are placed into your schedule ("call day"), and other days you work a usual/shorter shift.
