how do I cancel my shift ?

Hi there, @lina-alba.

Thanks for taking the time to reach out to the QuickBooks Community. How are you doing today? I hope all is well. 

You can make edits to your schedule and save them. Here's how: 

1. In QuickBooks Online, go to Time, then Time team, and select Schedule.
2. Click on the shift, then Edit. Make the changes, and choose Publish.
3. Drag the shift, and tap Publish.

That's all there is to it. For more information about this process, check out Manage shifts for QuickBooks Online. 

Please don't hesitate to let me know if you have any additional questions or concerns. I'm happy to lend a hand. Have a good one!
