Explanation:
The formation of groups of individuals is natural in any environment. In the organizational environment, groups can be formed according to social needs or achievement of organizational objectives and goals. People create groups so that they can interact with each other, exchange experiences, talk, work together and form social bonds.
Formal groups are those created by an authority whose objective is to integrate activities to achieve goals.
Informal groups are those formed by the people themselves, according to affinities, and attitudes.
Informal groups should be analyzed by managers more carefully, as the form of relationship between participants in an informal group can directly impact performance and organizational culture. Therefore, it is necessary that the manager helps the groups to develop social circles, which are necessary for motivation at work and a healthy organizational environment, but that present rules of conduct regarding ethics and behavior in the workplace.
