How should breaks be deducted? Separate duration from pay rules
The work-hours tool performs subtraction. It cannot decide which breaks are legally or contractually unpaid.
Work hours →Check that the durations are possible
A shift from 08:30 to 12:30 lasts four hours. Subtracting a 15-minute break leaves 3.75 hours mathematically. Entering 300 break minutes would exceed the entire 240-minute interval and should be rejected rather than producing negative work hours. An impossible break total often indicates the wrong unit or a transcription mistake.
Combine separate deductible intervals carefully
If the relevant records contain breaks of ten and twenty minutes, their total is thirty minutes. Whether those intervals should actually be deducted must come from the applicable pay arrangements, not from the existence of a break field. Also note that half an hour is thirty minutes, not 0.5 minutes. The time converter can check that relationship before the value is entered.
Build a schedule from verified shifts
Calculate each shift first, then combine the durations for the dates actually worked. The business-days tool can help count scheduled dates but does not know the length of each shift or any overtime rule. Keep the underlying break records and the rule used for deduction with the totals. That makes it possible to review a discrepancy without trying to reconstruct everything from a single rounded number of hours.
