How do I cancel a work schedule assignment?
In Transactions → Work Schedule Assignments, click Cancel at the end of the row and confirm the prompt ("Cancel this schedule assignment?"). Rows that are already cancelled show a dash instead of the button. The assignment's status becomes Cancelled and, from that moment, the employee resolves back to the next tier — a prior assignment if one still covers the date, otherwise their profile default, otherwise the company default.
Cancelling does not undo a Permanent assignment's profile update. If a Permanent change was made in error, also correct the Work Schedule field on the employee's profile.
