Titles don’t always illustrate the true scope of control. In large companies, layers of HR executives can exist. In these cases, you could have HRVPs report to senior HRVPs or chief people officers (CPO) or chief human resources officers (CHRO). There is a great deal of inconsistency because company size plays such an important role in structure and title so that HR directors in large companies can exist with far more scope, responsibility and compensation than CHROs in smaller companies.
