Assuming a 40-hour work week and all other things being equal, what would your ideal hours be if given a choice? You will be paid the same no matter how long your shifts are (no OT for 8+ hour shifts), and you are working exactly 40 hours a week. Assume these hours are feasible for your profession, even if they really aren’t.

Note on poll: note that from 5 days/week down, a distinction is made between consecutive and non-consecutive work days.
