What Is Shift Differential Pay?
A shift differential is extra pay for working less desirable hours — nights, weekends, holidays. No law requires it; it's a market tool for staffing the shifts nobody wants.
Typical differentials
Common structures: a percentage bump (5–15% of base rate for evening or overnight shifts) or a flat add-on ($0.50–$2.00 per hour). Healthcare, manufacturing, security, and hospitality use them most.
Calculating it
Flat: $18/hour base + $1.50 night differential = $19.50 for night hours. Percentage: $18 × 1.10 = $19.80. Pay the differential only for the hours actually worked on the qualifying shift.
The overtime catch
Shift differentials are part of the FLSA 'regular rate.' If an employee works overtime in a week that includes differential hours, the 1.5× overtime rate is computed on the blended average rate — not the bare base wage. Skipping this is a common audit finding.
FAQ
Is shift differential required by law?
No federal or state law requires it — it's an employer policy or union-contract term. Once promised, though, it must be paid as agreed.
Does shift differential count toward overtime?
Yes. It's included in the regular rate, so overtime is 1.5× the blended rate including the differential.
