At 14 you can not work more than 6 days a week. Not after 9pm or before 7am and not duribg school hours. You can work 10 hours in a day but as long as your average for the week is 8hrs max per day.
Possible with work permit and if I remember also only 30 hour per week but that might be during school time.
