A part-time job refers to positions that are scheduled for less than full-time employment. In practice, that usually means between 20 and 30 hours per week, compared to full-time employees who work 40 hours a week. Employers may schedule part-time workers in a variety of shifts, depending on the industry; shifts typically last three to eight hours and may be during standard business hours or on nights and weekends. Part-time positions often lead to full-time roles after an employee has proven to be reliable and proficient in specific job duties. You can find part-time jobs in almost every industry, but they are commonly found in fast-food restaurants, retail stores, and hospitality establishments.
