When using the Employee Scroll time clock format.
By default employees are displayed in the time clock portal only if they have a shift scheduled for the day.
Please check to make sure that your employee is listed on the published scheduled. If you need to make changes and add them to the schedule make sure to refresh the time clock portal in your browser once you have published the shift changes.
It is possible to allow any employee to clock in/out regardless of whether they are on the schedule. Navigate to the Time Clock Settings.
You can also control it on a per employee basis by opening up the employee's settings, navigating to the Employment Information area and selecting the box next to Can Clock In/Out without being scheduled.
You can enable for all employees from the Time Clock Settings. The setting you want to change is Employees appearing on the time clock portal.
