The third part of the Human Rights is more about collective freedoms, rights that can be exercised in the context of collective societies. At all time, people must access healthcare. The conditions for their wellbeing must be assured, under the protection of states or associations. Their right to security must be insured, even in the event of unemployment, sickness, disability, widowhood, old age or other lack of livelihood in circumstances beyond their control.
Let's see some examples of articles :
Article 20.
(1) Everyone has the right to freedom of peaceful assembly and association. (2) No one may be compelled to belong to an association.
Article 24.
Everyone has the right to rest and leisure, including reasonable limitation of working hours and periodic holidays with pay.

(2) Motherhood and childhood are entitled to special care and assistance. All children, whether born in or out of wedlock, shall enjoy the same social protection.
