Win by being nice, not nasty
I recently observed a supervisor loudly criticizing an employee in front of several customers. The supervisor achieved resentment from his employee and bad feeling from this customer. And does work improve with that type of criticism – almost never.
A more logical and effective supervisory approach is a calm clear conversation regarding the assignment at hand. A definition of the main goals followed by a discussion of the tasks will likely lead to improved performance, a sense of mutual respect and certainly a reduction of stress.
Leaders who teach achieve results and earn respect.
