Creation of contingent worker role

Content

I have a security requirement as follows

Contingent worker should have access to only directory-public information like name, primary phone details, address, line manager. Contingent worker should not be able to access their own personal information except public details. Contingent worker should not be able to access any other information that is usually available to a worker like personal information etc.

Please advise how I can create a contingent worker role like that.
