Since you can’t manage what you don’t measure, Sling's Premium and Business subscriptions include a weekly overtime calculator and overtime alerts, so you can spot and avoid potential overtime before it becomes a problem. (Daily OT settings coming in the future.)
To start measuring overtime and activate overtime alerts you need to enable the function in your Labor Cost settings (Dashboard > Settings > Labor cost). Here, you will specify when weekly overtime should kick in along with the multiplier rate (e.g. time and a half).
Once these settings are in place, you will receive a notification whenever you are about to schedule someone beyond the overtime threshold. You'll also see how many overtime hours you've scheduled so far and how much they'll cost your business.
