Final answer:
An organization is a group of individuals collaborating to attain common goals or interests, and may come in forms like formal organizations, labor unions, and corporations, all mandating differing commitment levels.
Step-by-step explanation:
An organization is indeed a group of people working together to achieve a common purpose. This common purpose can range from shared interests to achieving specific tasks or goals. Organizations can take various forms, such as formal organizations, labor unions, or even business entities like corporations and general partnerships. Formal organizations tend to have large, impersonal structures with a hierarchy of authority and impersonality at the core of their operations. Labor unions, on the other hand, focus on supporting their members through better wages and conditions, and corporations are authorized groups that act as single entities to make a profit.
Different organizations require different levels of commitment and structure for participation. For instance, professional organizations might require membership for practicing a profession, such as the American Bar Association for lawyers. In all cases, however, the key element that defines an organization is the group of people coming together for a concerted effort towards a shared objective.
