Part-time jobs that fit around childcare

A grocery chain and a hotel near Seattle are hiring part-time staff. There are 5 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?

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

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