An organization is a collective of people working together systematically to achieve a common set of goals. Formal organizations are established with specific objectives in mind. However, informal organization theorists recognize that there will always be an informal group within the formal structure. Formal organizations have planned responsibilities, consistent functions, and a structured hierarchy of authority and communication. For instance, a hotel is a formal organization with professional management and staff who have designated responsibilities and tasks. In contrast, informal organizations are loosely structured and fluctuate with the spontaneous membership of individuals. The kitchen staff in a hotel, for example, can be considered an informal organization as they are independent individuals without a specific system to control their behavior. The structure of authority and communication in the kitchen is not strict, and they work together to ensure the job is done
