29 CFR § 778.202 - Premium pay for hours in excess of a daily or weekly standard.
(a) Hours in excess of 8 per day or statutory weekly standard. A written or unwritten employment contract, agreement, understanding, handbook, policy, or practice may provide for the payment of overtime compensation for hours worked in excess of 8 per day or 40 per week. If the payment of such overtime compensation is in fact contingent upon the employee's having worked in excess of 8 hours in a day or in excess of the number of hours in the workweek specified in section 7(a) of the Act as the weekly maximum and such hours are reflected in an agreement or by established practice, the extra premium compensation paid for the excess hours is excludable from the regular rate under section 7(e)(5) of the Act and may be credited toward statutory overtime payments pursuant to section 7(h) of the Act. In applying the rules in this paragraph (a) to situations where it is the custom to pay employees for hours during which no work is performed due to vacation, holiday, illness, failure of the employer to provide sufficient work, or other similar cause, as these terms are explained in §§ 778.216 through 778.224, it is permissible (but not required) to count these hours as hours worked in determining the amount of overtime premium pay, due for hours in excess of 8 per day or the applicable maximum hours standard, which may be excluded from the regular rate and credited toward the statutory overtime compensation.
(b) Hours in excess of normal or regular working hours. Similarly, where the employee's normal or regular daily or weekly working hours are greater or fewer than 8 hours and 40 hours respectively and such hours are reflected in an agreement or by established practice, and the employee receives payment of premium rates for work in excess of such normal or regular hours of work for the day or week (such as 7 in a day or 35 in a week), the extra compensation provided by such premium rates, paid for excessive hours, is a true overtime premium to be excluded from the regular rate and it may be credited toward overtime compensation due under the Act.
(c) Premiums for excessive daily hours. If an employee whose maximum hours standard is 40 hours is hired at the rate of $12 an hour and receives, as overtime compensation under his contract, $12.50 per hour for each hour actually worked in excess of 8 per day (or in excess of his normal or regular daily working hours), his employer may exclude the premium portion of the overtime rate from the employee's regular rate and credit the total of the extra 50-cent payments thus made for daily overtime hours against the overtime compensation which is due under the statute for hours in excess of 40 in that workweek. If the same contract further provided for the payment of $13 for hours in excess of 12 per day, the extra $1 payments could likewise be credited toward overtime compensation due under the Act. To qualify as overtime premiums under section 7(e)(5) of the Act, the daily overtime premium payments must be made for hours in excess of 8 hours per day or the employee's normal or regular working hours. If the normal workday is artificially divided into a “straight time” period to which one rate is assigned, followed by a so-called “overtime” period for which a higher “rate” is specified, the arrangement will be regarded as a device to contravene the statutory purposes and the premiums will be considered part of the regular rate. For a fuller discussion of this problem, see § 778.501.
(d) Hours in excess of other statutory standard. Where payment at premium rates for hours worked in excess of a specified daily or weekly standard is made pursuant to the requirements of another applicable statute, the extra compensation provided by such premium rates will be regarded as a true overtime premium.
(e) Premium pay for sixth or seventh day worked. Under sections 7(e)(6) and 7(h), extra premium compensation paid for work on the sixth or seventh day worked in the workweek (where the workweek schedule is reflected in an agreement or by established practice) is regarded in the same light as premiums paid for work in excess of the applicable maximum hours standard or the employee's normal or regular workweek.
