Nanny family put the kids in school

Just a quick vent. I on my second week working what was supposed to be a long-term job. Nannying two young children. The family tell me how much they love having me and blah blah blah. Just after week 1, to say the oldest is enrolled in school, and I would only nanny one kids with pick up/drop off for the other. Now, on week two, both kids will be in school mid sept and ill out of a job. Had I known they enrolled the kids, i wouldn't have taken the job. Now I'm in a tough spot. I know we are nannies. But im an adult woman with responsibilities. It's not fair for nanny families to be so inconsiderate and inconsistent.
