Once your manager publishes the open shifts, you can easily pick them on your Android phone. On your Android Humanity app, tap on the 3 vertical lines and tap on ShiftPlanning from the left panel.
On the ShiftPlanning panel, click on "Pick Up" at the top and it will show you the open shifts.
Navigate to the date on which the open shift was posted by using the small arrows. Once you view the shift, tap on the shift and you can view all the shift details and request to work on this shift.
Tap on the shift and it will show you the shift details and request to work option. Tap on "Request to Work" to send the request to your manager.
You can always cancel your request any time if it is still under approval.
