Sling's Premium and Business subscriptions include a daily double overtime calculator so you can spot and avoid potential overtime costs before they become a problem.
To start measuring daily double overtime, you need to enable the function in your Labor Cost settings (Dashboard > Settings > Labor cost).
Once enabled, employees will receive twice their regular pay after 12 hours worked in a day.
You will then be able to see double overtime hours in your Reports; it has its own column.
Note that daily double overtime and weekly overtime are NOT compounded. If a shift exceeds the daily double overtime threshold, those hours will not contribute to the weekly overtime.
