A ministry of social affairs or department of social affairs is the common name for a government department found in states where the government is divided into ministries or departments. While there is some variation in the responsibilities of such ministries, the common thread between them is their responsibility for assisting members of society who are in a vulnerable position for example due to age, dependence on government aid, or being the employee in an employee/employer relationship. Ministries of this type cover matters such as social work, social protection and assistance, pensions, welfare, health and social security, and workplace standards for employees
