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.

One way to view unavailability is from the employee list. Open the employee list, then select the name of the employee whose unavailability you want to review. Once you are in the employee profile, select the Unavailability tab. This page is also where you can add a new unavailability set if needed.
Another way to review unavailability is from the Schedule tab, where there is a tab dedicated to unavailability. This view provides an overview of employees' unavailable times during the date range currently in view. From this view, selecting any of the gray blocks takes you directly to that set in the employee’s profile.
From the mobile app:
Note: Admins must have the Employee activity notifications setting enabled to receive notifications for changes made to employee unavailability.
If you want employee changes to unavailability to go through management for review, an admin can enable the unavailability approval setting included with Premium and Business subscriptions.
To enable approval for unavailability:
Any future changes employees make to their unavailability will appear on your Dashboard as requests. You can approve or deny a request directly from the main view, or you can select the notification to review the details of the requested changes. Pending changes are highlighted, and the dates and times appear in yellow on the grid. If the set is approved, Sling confirms the action and notifies the employee. The grid then changes to display the standard gray blocks.
On the employee side, a notification confirms the approval. Approved sets can no longer be edited by the employee. Changes to an existing set must be submitted again as a new request. Employees can copy a set to make changes without recreating the entire set.
Admins and managers can still make changes to an employee’s unavailability on the employee’s behalf at any time, so small edits can be completed without the employee having to recreate a set.
From the web:
You will receive a pop-up notification confirming that the request has been submitted.
Once your manager reviews the request, you will receive a notification of their decision, whether approved or denied.

If you need to check when a time off request was submitted, you can find this information in two places.
Admins and managers can review the web Dashboard. The notification includes a timestamp that is visible when you hover over the notification. If the request was submitted some time ago or has been pushed down by newer notifications, you can go to the schedule to see the history. Employees can also use this view to see details about their own time off.
To view the time off history from the schedule page:
These steps set the main PTO rules for the account. Once the account-level settings are in place, you can also set individual PTO caps in employee profiles.
To set up paid time off:
The main cap settings are also reflected in each employee’s profile and can be adjusted individually for employees who are not yet eligible or who have earned more based on length of service.
Note: Sling does not allow custom PTO categories. There is an Other option that you can use if you need a category that is not included in the standard list.
If employees are allowed different PTO amounts per year, you can set individual time off caps within each employee profile.
To set up individual PTO caps:
If you are using the paid time off feature, you can track paid leave along with related hours and costs on the Payroll report.
The approved hours for the selected date range appear under the PTO column. PTO costs are calculated using employees’ base wages. These PTO costs are then added to the Total wage column along with regular hours, overtime hours, and holiday hours, if any.
Note: PTO hours are not included in the Hours column. The Hours column reflects worked hours only, including regular, overtime, and holiday hours.
If editing is disabled, your employer requires approval for changes. Contact your manager to update your unavailability.
If you are unable to request time off, your employer does not have this feature enabled on the account. Contact your manager to update your time off.
Admins and managers add time off directly to the schedule.
If you are a manager and you have a manager assigned to your profile, your time off request will be sent to them for approval.
