This article explains how to block out time on the calendar if a staff member is running late for their shift.
You can add a break to the appointments calendar to mark a staff member as late. If a staff member is running late, and it's not their fault, you can add a paid break to block out that time on the calendar.
Select a timeslot where you want to create a break and click the Add break button, in the window that appears.
In the Label, indicate that the staff member was late for their shift. Then, select the Duration of their delay in minutes.
To mark a staff member's absence, leave the Paid break toggle turned off (this will ensure your reports are accurate). This means that the staff member will not be paid for the absence when you run the payroll report.
Having the break on the appointment calendar allows you to see it at a glance.
