To delete or Unassign a single shift, simply click on the shift to open the Shift Change window and then click the Delete button or set the helper to None. The Sortable List weekly Schedule View can be used to delete or Unassign (clear) a number of shifts all at once.
2. Check the boxes next to the shifts you want to delete (at the bottom of the page is a "Select All" link)
3. Click the Delete Selected Shifts link
If you make changes to a published schedule, the affected helpers are automatically sent notification messages if the "Send notifications" box at the top of the page is checked and if the helper has chosen that notification.
