Shift differential
A shift differential, also called a shift premium, is extra pay added to an employee’s base wage for working a less desirable shift.
Typical examples are overnight, weekend, and holiday shifts, rather than a standard daytime schedule. You set the differential as a flat amount per hour or a percentage on top of the base hourly rate. No federal law requires shift differential pay for private employers; it is generally voluntary or contractually negotiated, and states can differ. Hospitals, manufacturing plants, and call centers rely on it to keep less popular shifts staffed. Once you offer it, the differential must be factored into overtime calculations correctly.
Which shifts carry a differential, and how does it affect overtime?
A shift differential is generally part of a non-exempt employee’s regular rate under the Fair Labor Standards ActFLSA. The Fair Labor Standards Act (FLSA) is the federal law setting minimum-wage, overtime, recordkeeping, and youth employment standards for covered employment.Click to open the term. The week’s differential raises the regular rate for that week’s overtime, including overtime hours on shifts without a differential. The exception is a premium of at least time and a half that the Act treats as an overtime premium. Such a premium, for example one for weekend or holiday work, can be excluded and credited toward overtime owed. A flat overtime rate that leaves out the differential risks underpaying overtime.
| DIFFERENTIAL | WHEN IT APPLIES |
|---|---|
| Night | Hours in a defined overnight window, such as 11 p.m. to 7 a.m.; the most common form |
| Weekend | Hours worked on Saturday or Sunday, regardless of time of day |
| Holiday | Hours actually worked on a recognized holiday, separate from holiday pay for a day off |
| Split shift premium | Generally required by some states, such as California: one hour’s pay at the minimum wage, on top of that day’s minimum wage, when unpaid breaks you set (other than meal or rest periods) split the workday |
