Flexible summer jobs are part-time positions that are primarily available to students and professionals who do not work during the summertime, such as teachers. These seasonal jobs do not usually occur on a regular schedule, and duties can vary widely. A tutor or private music teacher offers lessons in the evenings or on weekends. Some teen students work in babysitting, pet-sitting, or lawn care positions, performing their duties on an as-needed basis. Flexible summer positions are also available at summer camps and recreational facilities, where your responsibilities are to plan and oversee activities or educational programs. You can also find posts with limited hours with retail or restaurant businesses.
