1. In a family every member is related due to some type of relation. We can find different types of cooperation-direct and indirect, primary and secondary in days of crisis as well as during the day to day routine.
2. Family members cooperate with each other in terms of sharing economic, emotional and social requirements of one another. If one of the members falls sicks or comes under mental tension for certain reasons, all other members, leaving aside their routine work, give special attention to the ailing member. If one is busy in seeking appointment with the doctor and taking the ailing member to the doctor or getting medicine for her, others are busy in making the prescribed diet or are with her and attend to her routine requirements. It is due to the cooperation of family members, the person in distress is able to cope up with the stressful situation.
3. Co-operation at the level of family is not necessarily to be understood at the time of crisis. In everyday life, the members co-operate with one another in terms of meeting day-to-day household requirements.
4. Collection of fire-wood or arranging for other sources of fuel, grinding of the cereals, buying of vegetables, cooking, taking care of children, looking after domesticated animals, watering the plants and fetching or storing the water all the smoothly possible when the family members cooperate on a daily basis.
The underlying principle of division of labour makes this kind of co-operation possible.
