Best Answer: It really depends on the owner/operator of that specific Chick-fil-a. By law someone as young as 14 and 15 can work, but the hours and work they can do is so limited that most owners choose to only hire 16 and up. Just call the location you are interested in and ask. additional details... during school weeks you can only work 3 hours per day and up to 18hours in a total week. at that age you aren't allowed by law to climb a ladder...use a knife and almost everything in the kitchen is age restricted to at least 16-18.
