What Is a Shift Differential?
A shift differential is extra pay for working less desirable hours, such as evening, night, weekend, or holiday shifts. It is usually a fixed amount added per hour or a percentage of the base rate. In the United States it is generally not required by federal law but is common in healthcare, manufacturing, and other 24-hour operations.
Example
A 1.50 per hour night differential on a 20 base rate gives 21.50 per hour for night shifts. A 10% differential would give 22.
