Training
Training is teaching, or developing in oneself or others, any skills and knowledge that relate to specific useful competencies. Training has specific goals of improving one's capability, capacity, productivity and performance. It forms the core of apprenticeships and provides the backbone of content at institutes of technology (also known as technical colleges or polytechnics). In addition to the basic training required for a trade, occupation or profession, observers of the labor-market recognize as of 2008 the need to continue training beyond initial qualifications: to maintain, upgrade and update skills throughout working life. People within many professions and occupations may refer to this sort of training as professional development
Manager
As far as possible the duty of a leader is to foresee dissatisfaction and to remedy injustice before complaints are made. To accomplish this he must maintain close contact with the men he controls. Let him go into the trenches if he is a general; let him arrive at the factory with his workmen now and then if he is the manager. He must have some imagination; an understanding of other men's lives is necessary to him, so that he may be able to protect those under him from unnecessary suffering. The secret of gaining their affection is to feel affection for them and to be able to do their jobs as well as they do them themselves. Men endure taking orders, and even like it, if the orders are given intelligently.
André Maurois The Art of Leadership
