Evening and part-time openings around Tucson after 9 years as a quality inspector

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

Thanks for writing this out. I went through something close to it last year, and it got easier once I kept a simple log of every call and form.
