When someone is late for a shift you can record it in RecStaff for both timesheet and reporting purposes.
Open the shift on the Employee Shift panel by clicking on it.
Click the Edit Shift button at the bottom of the Shift Details dialogue.
Change the start time of the shift.
Click on the Coding tab to add the Started late Work Code and Save Changes.
Now when you look at the Employee Shift panel you'll see the work code. You can view this from the history tab as well and run the Work Code Stats report under the Reports menu option.
