To cancel a shift, complete the following:
1. Open the Qwick Professional App
2. Click into the 'My Shifts' section
3. Click on the shift you wish to cancel
4. Click on the red 'Cancel Shift' button
Remember, cancelling will always negatively affect your QwickScore. The sooner you cancel, the less it will affect you. It is best to only accept shifts you know you can make, so that cancelling does not affect your future invites.
