Evening and part-time openings around Birmingham - what worked for you?

A cleaning company is taking applications for evening crews. There are 15 people counting on me, so I am trying to be careful. They can give a schedule two weeks ahead. 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.
