Cooperation means working together it is a social process. Cooperation plays a very important role in the society. According to Durkheim, "Solidarity is important to understand cooperation in society"

He has divided it as -

Mechanical Solidarity - This form of unity is based on similarity. Most of the people in society live very similar lives with little specialisation, which is associated with age and gender. These members feel united by the belief they share, their common sentiments, and the common conscience and consciousness.

Organic Solidarity - This form of unity is based upon the division of labour and results due to interdependence among the members of the society. Specialisation brings dependency with it. Industrialisation is more about specialisation and is related with the unity which requires both cooperation and coordination without which it is difficult to achieve the desired objective.
