Part-time Jobs for Children

In Britain, children can have a part-time job when they are thirteen. A lot of teenagers work in the evenings or at weekends as assistants at some shops, or in restaurants and fast-food places. Others choose to deliver newspapers before they go to school in the morning. Girls often find work as babysitters for busy parents. In Westminster Secondary school near London, sixty percent of students say that they have a part-time job. Most say that they use the money from their jobs to buy new clothes and CDs or comic books. Part-time jobs are often hard and not very exciting. Most part-time jobs don’t get much money, but children can get important work experience and learn many things about the world.
