I work nights in a LTC facility. My usual schedule works out to 40 hours per week plus a little incidental OT- Mondays and Thursdays I work 2200-0600, Tuesdays and Wednesdays 1800-0600. It's actually kind of nice starting and ending my work week on a short shift.
We often find ourselves straining the nursing roster and shorthanded- not because of high turnover or anything (it's actually a fantastic, well-managed 5 star facility that treats their employees like royalty) but because we get a lot of brand spanking new nurses apply and get hired here for their first job but then jump ship as soon as a coveted and elite position in the hospital next door opens up. Age old tale, hehe. Also we just had two nurses retire, a floor nurse get promoted to DON, and one nurse is out convalescing from a knee surgery.
As a result, in the two years that I've worked here, I've had to do some stretches of four 12's or even five 12's in a row to fill some gaps, and I am at this moment in week one of a six week stretch of four 12's. It's not awesome, but they make stepping up and helping out worth my while- in addition to the 8 hours of OT each week it adds up to, I get a $100 "pick-up" bonus for each day I work extra hours- that's an additional $200 a week which is pretty sweet- even if it is pretax.
