Question: how long can you work when you are 15?
Answer: 14-year-olds and 15-year-olds can work, but have the most regulations in place--you can't work more than 18 hours in a school week or 3 hours per day on a school day. You'll be happy to know that these times are extended during the summer and school holidays to 40 hour work weeks and 8 hour days.
