You can end a shift pattern in 2 ways: individually, or for multiple employees at a time.
Ending a shift pattern for one employee
In your Scheduler, find the employee and the shift pattern you want to end.
Highlight the shift pattern, then click the three-dot menu.
Click Clear pattern from this day onward.
Be sure that your Scheduler is viewing the appropriate week where you want the shift pattern to end.
Ending a shift pattern for multiple employees
In the Scheduler, click on the File menu.
Click on 'Clear multiple patterns' to bring up the below modal:
Select the start date of the pattern you want to clear.
Choose the employees for whom the pattern should be cleared.
Click the 'Clear employees' button.
You can also make quick or detailed adjustments to a shift pattern, or also assign an existing shift pattern to another employee.
