Learn how to use the unavailability and time off features within Sling.
This can be used for full or partial days. You can enter a request that spans multiple days as well.
Note: Availability of these features depends on employer settings.
Sling's Unavailability feature is available with Premium and Business subscriptions.
Unavailability shows when you cannot work and repeats based on your schedule needs.
Unavailability will always show as a week's time frame when viewing the list of sets, even if only one day is set as unavailable.
