- Averaging the two weeks' hours instead of checking each week against the 40-hour overtime threshold independently
- Miscounting a shift that spans the boundary between two pay periods as belonging entirely to one period
- Using 24 periods/year instead of 26 when annualizing a bi-weekly figure
- Applying a single pay rate to the whole period when a rate change actually occurred mid-period
- Blending PTO hours into the worked-hours total used for a specific week's overtime calculation
The Common Thread
Most of these mistakes come from treating the bi-weekly period as the unit of calculation, when the actual legal and practical unit for most of these questions (overtime, rate changes, PTO interaction) is the individual week within that period — checking each week's figures independently before combining them into a period total avoids the majority of these errors.
