When shutdown days have been pushed to employees, time off records are created for the employees in question, these are visible within Time and Attendance -> Time Off as well as within the Calendar.
There may be occasions where you need to cancel or remove the shutdown day. The record itself can be removed, however, this would not remove the corresponding time off records.
To assist with this, there is an option in
Time and attendance -> Holidays
Once on this page you can search for the shutdown day you'd like to remove from employee calendars and click Actions -> Delete all shutdown records on this date.
PLEASE NOTE: This option is only available for admin users.
Once this option is selected the booked time off that was added when the shutdown day was originally pushed will be deleted. This will only remove the time off booked for the shutdown day, if there is time off booked outside of the shutdown, this will not be deleted.
