“Managers in different parts of the world are conditioned to give feedback in drastically different ways. The Chinese manager learns never to criticize a colleague openly or in front of others, while the Dutch manager learns always to be honest and to give the message straight. Americans are trained to wrap positive messages around negative ones, while the French are trained to criticize passionately and provide positive feedback sparingly.”
