Overnight care, early arrival and late departures

[mom-in-alberta]

As a provider, I would not be able to do those hours, period. It just doesn't work for our family scheduling, or my sanity! But if that is the norm for your area, and you find that you must; then you deserve to get paid more, for sure!!!!
If someone is working 12 hours, then typically (as playfelt mentioned) they get a shortened work week. OR: more money. So should you. Either charge more on a daily basis, or agree that your full time rate will allow for 4 days instead of 5.
