Childcare question: Do you think it is fair or unfair to expect a child care job that you have been ?

consistently showing up at 6am to and have called in sick 1 time in 4 years, to pay you for time off because of school recess? The children taken care of are twins and are now 9 yrs old. Both parents work high paying jobs and need child care each morning from 6 to 8, and then again 3:30 to 4:30Pm. need a fair and rational answer! Thanks so much!
