Document Type Security Profile - Visibility issue

Hello experts,

we have a request from a client to create two different document type:

• One for the employee: only employee should see this doc (eg. selfevaluation)
• one for manager and HR: only manager and hr should see this doc (eg. performance evaluation)

Anyway if for the workers who are manager and HR we add the role of the employee, then these workers will not only the document performance evaluation of the employee but also his/her self-evaluation.

We check the document security profile and the document type but it seems that if we add that role of employee, then this grants the vision of the document.
