Flexible shifts hiring in San Diego - 3 weeks in

I am looking for part-time work that fits around school hours and found a few evening shifts near San Diego. It has been weighing on me all week. Some roles have a small tuition benefit. Is the schedule really fixed?

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

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