The concept of a welfare state is a system of government that aims to improve the welfare and quality of life of its citizens, including basic needs such as health, education, housing, and social security. A welfare state seeks to reduce social and economic disparities through income redistribution and equitable fiscal policies. Workers play a key role in social welfare development. Employment is a vital issue for many people and ultimately reflects the level of progress of a country's development. Workers must earn a decent living. This aligns with the demands of a welfare state to protect the people from negative aspects. Indonesia, as a country that adheres to the principles of a welfare state, carries out national development, particularly in the development of quality human resources, such as workers.
