To elaborate on this, I have two locations in my company, One main branch, and another sub-branch, both have HR managers, HR Managers have a responsibility to pay the salary of that particular location's employees.

Now, I don't want to show all the employees' salaries/net wages to every HR manager.

Is there any way, where the HR of the sub-branch can not see the main branch's employment & employees' wages?

However, the HR manager of the Main branch can able to access all the employees in the company.
