Organizations such as the International Labour Organization (ILO) and the United Nations (UN) actively promote the World Day for Safety and Health at Work on April 28 every year. The International Labour Organization (ILO) started observing the World Day for Safety and Health at Work on April 28, 2003. The ILO is devoted to advancing opportunities for people to obtain decent and productive work in conditions of freedom, equity, security and human dignity. It aims to promote rights at work, encourage decent employment opportunities, boost social protection, and strengthen dialogue in work-related issues. The ILO celebrates the World Day for Safety and Health at Work to promote the prevention of occupational accidents and diseases globally. It is an awareness-raising campaign intended to focus international attention on emerging trends in the field of occupational safety and health and on the magnitude of work-related injuries, diseases and fatalities worldwide. The theme of the campaign for 2015 is: Join in building a culture of prevention on OSH.  A national occupational safety and health culture is one in which the right to a safe and healthy working environment is respected at all levels, where governments, employers and workers actively participate in securing a safe and healthy working environment through a system of defined rights, responsibilities and duties, and where the highest priority is accorded to the principle of prevention.
