How to prevent HR employees from viewing other HR employee data?

Is there a way to prevent users in the same department from viewing their co-workers personnel data but still allow them to view all non-HR employees’ personnel data?

                               

Ex.        Persons A and B are both HR employees.

 

            Person A should be able to view all employee data in the company.

 

Person B should only be able to view their HR data and non-HR employee’s data. Person B should not be able to view anyone in HR’s employee data.

 

Some of the fields/forms we would like to prevent employees from viewing are fields on the Benefits tab on the Person form, the entire Assignment form, Salary button, select element entries, and some OAB information.
