Under § 7(j) of the FLSA, hospitals and residential care establishments,  may, pursuant to a prior agreement or understanding with their employees, utilize a fixed work period of 14 consecutive days in lieu of the seven-day workweek for the purpose of computing overtime, if they pay time and one-half the regular rate for hours worked over eight in any work day or 80 in the fourteen day period, whichever provides the greater number of overtime hours. This rule is almost never used in practice, however, because it rarely results in a savings to the employer.
