Flexible shifts hiring in Omaha, HR coordinator here

I am looking for part-time work that fits around school hours and found a few evening shifts near Omaha. I am in Omaha, 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 11 months ago, and it settled down once I kept a simple log of every call and form.
