Part-time jobs that fit around childcare (update)

I am looking for part-time work that fits around school hours and found a few evening shifts near Little Rock. It has been weighing on me all week. Shifts are four to six hours and the pay is weekly. 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.

Check how they treat part-time staff for benefits. Some add them after a set number of hours.
