Flexible shifts hiring in Chicago - 13 months and counting

I am looking for part-time work that fits around school hours and found a few evening shifts near Chicago. It has been weighing on me all week. They can give a schedule two weeks ahead. 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 worked evenings at a hotel. The hours were steady and the team was friendly, but weekends were busy.
