As a teenager, your schedule is often demanding. Finding flexible, part-time work during high school is an excellent way to make extra money without interfering with your studies. After school jobs include babysitting gigs, entry-level positions in retail, or roles in the foodservice industry. Being a lifeguard or dog walker also allows you to create a part-time work schedule. Your responsibilities and duties vary by the job, but each is an excellent way to pick up necessary work skills for later in life. Many flexible jobs are seasonal, especially those that revolve around summer camps or swimming.
