Flexible shifts hiring in Phoenix - 23 weeks in

I am looking for part-time work that fits around school hours and found a few evening shifts near Phoenix. I worked as a customer-service rep before this. They can give a schedule two weeks ahead. Is the schedule really fixed?

Ask whether the schedule is posted in advance and how they handle swaps. It matters a lot with kids.

Check how they treat part-time staff for benefits. Some add them after a set number of hours.
