Flexible shifts hiring in Kansas City - first time posting

I am looking for part-time work that fits around school hours and found a few evening shifts near Kansas City. I have been trying to stay organised about it. 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.
