We have a client who has one person who oversees the hourly staff. We have them setup as a Featured Admin limiting their permissions to hide the income of salaried employees (using the Benefits & Billing Primary Subgroups).

For those subgroups that are checked, this featured admin can see/edit the salaries, while she will see only a blank field on those that are unchecked.

      

We realized there's a gap to these permissions as the salary is populated out to the carrier forms, which she can access on the Personnel File of any employee, no matter what subgroup they are assigned to.
