Evening and part-time openings around Tucson, teaching assistant here

I am looking for part-time work that fits around school hours and found a few evening shifts near Tucson. I have read a lot of threads here and could not find my exact situation. Some roles have a small tuition benefit. How many hours do they guarantee?

I got the job by going in around mid-morning and asking for the manager. Worth a try.

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