Clandestine employment is a sole or secondary gainful non-casual occupation that is carried out in violation of provisions set by legislation. In particular, it is characterized by non-compliance with labour standards and social security provisions on the part of the employer. Strictly speaking, remunerated work, which is not protected through contributions to the social security system, should be considered clandestine. However, there are different views of what constitutes clandestine labour in developed and developing countries, reflecting the strength and effectiveness of the relevant legal provisions in each country. Much clandestine employment is in the informal economy. However, clandestinity cannot always be equated with informality. Informal employment is more likely to be considered clandestine in the developed countries, whereas in most developing countries, where the majority of people may live in traditional social contexts and may not even be aware of national legislation, informal productive activities are not usually thought of as clandestine.
