Part-time jobs that fit around childcare, electrician's helper here

I am looking for part-time work that fits around school hours and found a few evening shifts near Baltimore. Shifts are four to six hours and the pay is weekly. Is the schedule really fixed?

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.
