You can add employee leave, such as annual, personal, or sick leave, into Traffio to mark a resource as unavailable on the booking board. Employees can enter their leave if self-managed leave is enabled on the mobile app, or office staff can input it on their behalf.
To input an employee's leave, you must have the "Leave approval access" permission enabled. If you want to create a specific leave type for unavailability, you can do this in Admin > Leave Types. Read more here
How To Enter Leave
Navigate to People on the sidebar
Select the Leave tab
Click +New
Select the Leave Type (It is recommended that a Not visible to workers leave type is used so the unavailability isn't shown as leave on the worker's app)
Pick the Date From and Date To (There isn't a limit to how long you can set this to)
Click Create
If an employee is unavailable on certain days, you can select which shifts they are unavailable for. They will be marked as unavailable for any shift that is turned ON.
