OP, as you seem he’ll bent your kid not being available, get creative. Your kid can babysit, tutor, do landscaping/ yard care in mornings or after hours, run errands, etc.

Employers don’t need the inconvenience of training someone who is never available, or won’t be.

I mean my kids all work during high school too. How do they have spending money if they aren’t working?

10-15hrs a week during high school
20-30hrs during summer
10hrs a week during college

Are they in band, sports, or other similarly time-consuming activities, as per the OP's question?

If her kid can’t commit to work for the summer, then she should pay him to work around the house or similar.
