In England teenagers aren't LEGAL/ LEGALLY allowed to work UNTIL/TO they're 13. A 13-year-old can only work up to two hours IN/ON a school day and up to five hours on Saturdays. During the summer break these limits are RISEN/RAISED to 5 hours a day. Older pupils (15-16) can work a bit longer. The problem is that before someone turns 18, the law doesn't set a minimum WAGE/MONEY, so teenagers are badly paid, or they're paid CENTS/PEANUTS as we sometimes say.
