Permissions Role assigns one of your Employee Profiles (created under HR Tools > Employees > Profiles) to the employee's user account, which decides what that person can see and do in the admin panel. Choose No Admin rights to remove admin access. The dropdown itself is shown whenever your own role has the Edit Users Roles permission; saving your selection additionally requires the Human Resources module — without it, your choice here is not saved. Saving it updates the user's role immediately.
