WorkRecords uses a convention called Weighted Allocation for distributing overtime when a worker moves across departments in the same week, as there is no way for the software to know which department "caused" the OT. To use an analogy, it's a little like asking someone which touchdown won the game? The first one or the last one? WorkRecords' formula allocates the overtime to each department based on the pro rata amount of time worked in each area that week

Jane Smith worked in both Department A and Department B during a week and generated 8.96 hours of overtime.
     25.13 hours - Department A
 +  23.83 hours - Department B 
     48.96 hours (8.96 hours of overtime)

Since WorkRecords splits OT proportionately, 51.3% of the overtime spend was allocated to Department A because 51.3% of her hours were worked in Department A and 48.7% of the overtime spend was allocated to Department B.

Remember, Labor Buyers have the ability to do an offsetting adjustment in their accounting systems, if needed, to reflect any changes to the overtime allocation to which each department agrees.
