Evening and part-time openings around Boise - any advice?

A grocery chain and a hotel near Boise are hiring part-time staff. I do not usually post, so bear with me. Shifts are four to six hours and the pay is weekly. How many hours do they guarantee?

Thanks for writing this out. I went through something close to it 3 months ago, and it settled down once I kept a simple log of every call and form.
