Hope you are a HR professional.... other than general HR activities...the HR's major role is a "CHANGE AGENT", change is painful but inevitable, change is continuous so as per the changing world the organization need to undergo lot of changes failing which the organization will perish as the competitors will over take.
Change should from the people, by the people & for the people so as a people man HR need to take charge of the change. HR is responsible for change in Technology, people, processes etc., etc., As I told the change is very painful hence people may not simply accept even management may not be ready for change with a fear of failures & losses.
As a change agent the HR need to face lot hurdles, resistance and this is mostly from the Top Management, top professionals, Seniors in the organization but you need to go on. Need one breakthrough & this specifically on financial front ie., once you succeeded in adding value to the
bottom line (profits) then you are accepted, appreciated, allowed & followed.
Considering the above facts you need to be very specific on your first change initiative because it is a do or die situation.
