The premium
When extra pay starts, what it multiplies, where the week begins and how it gets counted twice.
Where the Workweek Begins
Why the start of the workweek has to be fixed and written down, how a floating boundary changes what is owed, and what to check before changing it.
When the Premium Starts
The thresholds a premium attaches to, why the period it is measured over matters more than the number, and hours that count without being worked.
Paying the Premium on the Premium
The order of operations in a premium calculation, why including the premium in its own base compounds it, and the three ways systems get the sequence wrong.
Premiums That Are Not Overtime
Call-out minimums, unsocial hours, holiday working and the other premiums that live outside the overtime calculation, and how they interact with it.
Averaging, and What It Hides
What an averaging or annualised hours arrangement does to premium thresholds, the safeguards it needs, and three things to check each period.
Time Off Instead of Pay
How time off in lieu accumulates into a liability nobody tracks, the rate it has to be converted at, and what happens to a balance when somebody leaves.
The Week That Straddles Two Pay Periods
Why a workweek spanning a pay period boundary loses its premium in several systems, the two ways to handle it, and what to test.
