Found in the following reports:

Productive Hours = Working Hours − Break.

All worked hours count, including hours worked outside opening hours — before opening, after closing, or on days the location is closed.

Two optional features can be enabled to refine this: Employee Productivity and Task Productivity. If your company uses neither, the calculation above is the full picture. If these are enabled, it affects the result as follows.

This is a rate set per employee and is applied to their entire shift.

Productive Hours = (Working Hours − Break) × Employee Productivity

Example: An 8-hour shift with a 1-hour break, at 80% employee productivity.

A rate set per zone. Like Employee Productivity, it applies to the entire shift - a shift is assigned to one zone, so the rate covers all of its hours.

Example: The same shift, now placed in a zone rated at 90% productivity.

This is a rate set per task and is applied only to the hours spent on that task - not to the rest of the shift. Remaining hours use Employee Productivity alone.

Example: The same employee spends 3 of their 7 working hours on a task rated at 50% productivity.

The two rates compound rather than replace each other: one hour at 50% employee productivity and 50% task productivity yields 0,25 productive hours, not 0,5.
