Part-time jobs that fit around childcare after 3 years as a janitorial supervisor

I am looking for part-time work that fits around school hours and found a few evening shifts near Minneapolis. It has been a long 22 weeks. Some roles have a small tuition benefit. How many hours do they guarantee?

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

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