Yeah in PA anyone still in high school needs working papers. Chic fil A can be franchised, so the owners might not have known.

Its a bit confusing because you need a job to get working papers. Lol once you get the job and they give you a schedule you take it to the school office and they issue you working papers. There is strict rules for what a minor can work in PA.

Not your fault at all. You would expect a big place like Chic Fil A would tell you what you need to work there legally.
