Should I quit this job?

It was my first day at this daycare. I’ve been there from 8:20 A.M. to 6 P.M. with the exception of a one hour lunch break(I didn’t even like or need that much time honestly) after my lunch break(11 AM- 12 PM), they put me in a room with 5 toddlers with absolute no training and gave me little to no detail to maintain them. I had to figure it out by myself.

The daycare “coordinator” clocked me in really late, and I’m not getting my wholes day worth. I was basically there for a couple hours more for free.

Should I even stay at this job? It’s honestly frustrating.😫
