Full-time employment is employment in which a person works a minimum number of hours defined as such by his/her employer. Full-time employment often comes with benefits that are not typically offered to part-time, temporary, or flexible workers, such as annual leave, sickleave, and health insurance. Full-time jobs are often considered careers. They generally pay more than part-time jobs, and usually carry more hours per week. The Fair Labor Standards Act (FLSA) does not define full-time employment or part-time employment. This is a matter generally to be determined by the employer (US Department of Labor). The definition by employer can vary and is generally published in a company's Employee Handbook. Companies commonly require from 30–35 or 40 hours per week to be defined as full-time and therefore eligible for benefits. Full-Time status varies between company and is often based on the shift the employee must work during each work week. The "standard" work week consists of five eight-hour days, commonly served between 9:00AM to 5:00PM totaling 40 hours. While a four-day week generally consists of four ten-hour days; it may also consist of as little as nine hours for a total of a 36 hour work week. Twelve-hour shifts are often three days per week, unless the company has the intention of paying out the employee overtime. Overtime is legally paid out anytime an employee works more than 40 hours per week. The legal minimum for overtime starts at Base Pay + One-Half. The increased payout is considered to compensate slightly for the increased fatigue which a person experiences on such long shifts. Shifts can also be very irregular, as in retail, but are still full-time if the required number of hours is reached. There are some situations where a person who needs full-time work is dropped to part-time, which is sometimes a form of constructive dismissal to avoid paying unemployment benefits to a laid-off worker.
