Flexible shifts hiring in Denver after 10 years as a graphic designer

I am looking for part-time work that fits around school hours and found a few evening shifts near Denver. They can give a schedule two weeks ahead. Has anyone worked these shifts?

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

I worked evenings at a hotel. The hours were steady and the team was friendly, but weekends were busy.
