Part-time jobs that fit around childcare (update)

I am looking for part-time work that fits around school hours and found a few evening shifts near Memphis. I am in Memphis, in case local advice matters. Some roles have a small tuition benefit. How many hours do they guarantee?

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

I got the job by going in around mid-morning and asking for the manager. Worth a try.
