Short answer
Count eligible premium hours, multiply by the differential, and compare that amount with the shift premium or differential line on the pay stub.
Missing differential is easy to miss because base wages may still look correct. Look for the premium line, not just the total deposit.
Open Shift Differential CalculatorThe fast way to diagnose it
Working rule: Expected differential pay = eligible premium hours x differential amount.
Realistic example: If 18 weekend-night hours should receive a $2.00 premium, the expected differential is $36 before taxes.
Key checks
- List eligible premium hours.
- Confirm the differential amount or percentage.
- Find the premium line on the stub.
- Check whether overtime changes the differential treatment.
