29 CFR § 778.220 - “Show-up” or “reporting” pay.
(a) Applicable principles. Under some employment agreements, an employee may be paid a minimum of a specified number of hours' pay at the applicable straight time or overtime rate on infrequent and sporadic occasions when, after reporting to work at his scheduled starting time on a regular work day or on another day on which he has been scheduled to work, he is not provided with the expected amount of work. The amounts that may be paid under such an agreement over and above what the employee would receive if paid at his customary rate only for the number of hours worked are paid to compensate the employee for the time wasted by him in reporting for work and to prevent undue loss of pay resulting from the employer's failure to provide expected work during regular hours. One of the primary purposes of such an arrangement is to discourage employers from calling their employees in to work for only a fraction of a day when they might get full-time work elsewhere. Pay arrangements of this kind are commonly referred to as “show-up” or “reporting” pay. Under the principles and subject to the conditions set forth in subpart B of this part and §§ 778.201 through 778.207, that portion of such payment which represents compensation at the applicable rates for the straight time or overtime hours actually worked, if any, during such period may be credited as straight time or overtime compensation, as the case may be, in computing overtime compensation due under the Act. The amount by which the specified number of hours' pay exceeds such compensation for the hours actually worked is considered as a payment that is not made for hours worked. As such, it may be excluded from the computation of the employee's regular rate and cannot be credited toward statutory overtime compensation due him.
(b) Application illustrated. To illustrate, assume that an employee entitled to overtime pay after 40 hours a week whose workweek begins on Monday and who is paid $12 an hour reports for work on Monday according to schedule and is sent home after being given only 2 hours of work. He then works 8 hours each day on Tuesday through Saturday, inclusive, making a total of 42 hours for the week. The employment agreement covering the employees in the plant, who normally work 8 hours a day, Monday through Friday, provides that an employee reporting for scheduled work on any day will receive a minimum of 4 hours' work or pay. The employee thus receives not only the $24 earned in the 2 hours of work on Monday but an extra 2 hours' “show-up” pay, or $24 by reason of this agreement. However, since this $24 in “show-up” pay is not regarded as compensation for hours worked, the employee's regular rate remains $12 and the overtime requirements of the Act are satisfied if he receives, in addition to the $504 straight-time pay for 42 hours and the $24 “show-up” payment, the sum of $12 as extra compensation for the 2 hours of overtime work on Saturday.
(c) Show-up or reporting pay mandated by law. State and local laws may mandate payments or penalties paid to an employee when, before or after reporting to work as scheduled, the employee is not provided with the expected amount of work. All such payments or penalties paid to employees that are mandated by such laws and that are not payments for hours worked by the employee are excludable from the regular rate if such penalties are paid or payments made on an infrequent or sporadic basis. They cannot be credited toward statutory overtime compensation due.
