Final answer:
Management by setting a good example and fully dedicating oneself to one's job is referred to as Lead-by-Example Management.
Step-by-step explanation:
Managing people at work by setting a good example and by giving 100% of your time, effort, and enthusiasm to your own job is known as Lead-by-Example Management. This style of management contrasts authoritarian leadership that issues orders, democratic leadership that fosters group decision-making, and laissez-faire leadership that allows for autonomy among group members. It is especially effective in settings where the leader's behavior can directly influence and motivate others' performance and dedication to their roles.
