I too have a three day week minimum to help secure my income, some parents still try to push the issue though. If you dont already maybe you should add to your contracts that any part time is concidered contingent upon filling by full time. required you give a certain ammount time notice. Full time should out weigh part time, but you should state so in a contract to cover your butt for when a parent has a problem with it. I had someone who took my min. due for a good couple years ( the kid was a pain to care for, so it helped my choice) but I got an offer for full time and this "pain" part timer was taking the spot. sooo... I gave the "pain" parents the choice to pay full-time or loose their spot because someone else needed full time care.
