Part-time jobs that fit around childcare - 26 weeks in

I am looking for part-time work that fits around school hours and found a few evening shifts near Birmingham. Any experience at all would help. Some roles have a small tuition benefit. How many hours do they guarantee?

Check how they treat part-time staff for benefits. Some add them after a set number of hours.

Keep everything in writing and save the confirmation numbers. It made the follow-up calls so much easier.
