Evening and part-time openings around St. Louis - 2 months and counting

I am looking for part-time work that fits around school hours and found a few evening shifts near St. Louis. I have read a lot of threads here and could not find my exact situation. 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.
