Hmm ~ I am no help cause I would not be willing to do this ~ my family time, weekends and holidays are too important to me and well a child being away from their parents that long goes against every family value I hold dear ~ no amount of $$$ would make it worth it for me!

However my values aside I agree that anyone doing this should consider a serious 'shift premium' just like those workers in hospitals and factories get compensated with for working these kind of schedules

Prudent to be charging 'overtime' for going over 9 hours a day, an evening shift premium for working 'over night cause just cause the kid is sleeping you are required to sleep with one eye and ear open and I would definitely be doing double time for working any 'statutory holiday' and so forth as well as compensation for the lost income of holding a full time space open for someone who is only going to use 8 days a month!
