Role of a Benefits Broker

It surpises me today that the role of the benefits broker is still unclear with many businesses today. A Broker acts on the behalf of the client they serve. A Broker's fiducary is always to those firms they serve, not the insurance carrier. I believe a lot of decision makers in businesses think that if they buy a policy from an insurance company through a cetain broker, they are stuck with that individual. In fact a business can change their broker at anytime. The questions should be, which broker is going to service my firm and provide me with strageties to minimize adverse cost increases? Is that what your broker does for your firm?
