Flexible shifts hiring in Milwaukee - what worked for you?

I am looking for part-time work that fits around school hours and found a few evening shifts near Milwaukee. I am in Milwaukee, in case local advice matters. They can give a schedule two weeks ahead. 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.
