Clicking the search icon in the top right corner will open up the Organisation Structure. You can either expand each section to look at the employees in each post or you can search the employee by name.
If you are searching for a terminated user, please keep in mind that they will not be displayed when searching this way and that you will instead need to follow the steps below:
Go to Admin Menu, then All Employees.
Click Show Advanced Filters.
Scroll down to Status and deselect all.
Select Not Active and Terminated.
Click Filter.
