If we read the book of HR Value by David Ulrick, and considering the function of HR as Employee Champion, the said statement may be quiet classic in its nature.
As an HR practistionare, we should be able to gain confident and trust from the Management and our Employees. It is true that as an HR, we should be in the management side, however, it is not the way to put it...for me as an HR, we should be able to bridge the gap between the management and the employee alike.
It is a hard and challenging tasks indeed, however, it is possible to do it. Further, in the said book, the author extended the 'HR client' (our client as of present is more on the CEO or our Big Boss and the staff) includes also the External Customer of our line of business.
The second opinion may be, we as an HR should be able to bring confident in our staff, so that we can be able to motivate them to work productively by our 'Human Touch' (a long with the term used Human Resource Practitioners-->we are required to be more HUman in our approach to our customers both external and internal)
Therefore the buttom line of this is the HR himself/herself...how are we going to approach our employee?
