Flexible shifts hiring in Raleigh - first time posting

A cleaning company is taking applications for evening crews. I have read a lot of threads here and could not find my exact situation. Shifts are four to six hours and the pay is weekly. How many hours do they guarantee?

Keep everything in writing and save the confirmation numbers. It saved me later.

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