In order for an employee to be able to see other employee records, you will first need to make sure that they have access to the correct sections and subsection. To do this, please refer to our article on giving access to sections.
Once the correct level of access is assigned, the employee will have access to all employee records in the sections they can view.
The employee will also need the view permission called 'Employee Administration: Details' which can be added for them by following the steps in our article on adding permissions.
