Part-time jobs that fit around childcare after 16 years as an office manager

A cleaning company is taking applications for evening crews. I do not usually post, so bear with me. Some roles have a small tuition benefit. Is the schedule really fixed?

I got the job by going in around mid-morning and asking for the manager. Worth a try.

Ask whether the schedule is posted in advance and how they handle swaps. It matters a lot with kids.
