Full-time employment involves working a minimum number of hours defined by the employer. It often includes benefits like paid leave and health insurance. Part-time jobs involve fewer weekly working hours, usually less than 30-35 hours. Freelance workers are self-employed and not committed to a single long-term employer. Shift work divides the day into different shifts that various groups of employees rotate through. Permanent employees have a single long-term employer and receive benefits, while temporary employees have short-term contracts and may be called contractors.
