Also a phone notification that reads "Non working day leave request approved" will pop up.

Now your manager will know when you aren't available for shifts. 

If you need to change your availability it's as easy as repeating the process above.

This loads the calendar confirming which days you have made yourself unavailable.

When you select one of the dates, the details will be opened. Here you'll see a REMOVE link. Clicking this removes the unavailability and makes you available.

At this time it isn't possible to add multiple unavailable timeslots via the app.

The unavailability feature is relatively new, having been recently released we are evaluating its popularity before expanding the feature.

In time this will be possible via the app, however, staff the office team at your employer can add multiple unavailable times in a single day via the Scheduler interface.
