The term 'WORK FILL-INS' refers to a type of job that involves filling in for an employee who is absent or on vacation. The job is usually temporary and the person hired is referred to as a 'TEMP'. TEMPS are often used to fill in for short-term absences, such as maternity leave, or to cover for employees who are on vacation. They may also be used to fill in for long-term absences due to illness or injury. TEMPS are usually hired on a contract basis and are paid an hourly rate.
