The unorganised sector or the informal sector covers work activities that largely operate outside the control of the government. The unorganised sector generally includes labour force such as self-employed personnel, regular salaried employees, and casual workers. For example, fishermen, carpenters, cobblers, and plantation labourers.
However, the organised sector or the formal sector comprises enterprises or places of work that are registered with the government. For example, professions like doctors, teachers, and bank officers.
