To Delete a Shift on the By Helper Schedule View:

Normally it is best to use the By Helper Schedule View to edit, delete, clone or assign shifts because it allows you to quickly make changes without the page reloading. To delete a shift on that view, you can click the shift, and click the DELETE Shift button in the upper left. Deleting shifts is permanent and they cannot later be restored.

To delete more than one shift, it may be more convenient to use the Sortable List schedule view.

To Delete a Shift using other Weekly Schedule Views:
From any weekly schedule view (except the By Helper):

• (1.) Click on any shift to open the (2.) Shift Change window
• Make whatever changes are needed
• Click the DELETE Shift button in the top left of the window to delete the shift 
• Click OK
• The window will close and the schedule view will be updated 
• If the shift was on a published week, any affected helper may be automatically notified.
