The Subtract From Forecast mode subtracts unpaid employee lunch time from the Forecast hours in the Requirements but does not add time to the end of the shift. (Neither the Requirement or Schedule records start/end times will be modified.) For example, if the shift is a 7.5 hour shift and the employee has a 30-minute unpaid lunch, the employee's shift will be displayed on the schedule as 06:00 to 14:00 and the forecasted hours will be 7.5 hours. The schedule will show that the next employee's shift starts at 14:00, so there is no overlap in scheduling and the Requirements have been met.
