[Informal employment, unemployment and underemployment: a matter of public health]

Unemployment and underemployment are problems that have been studied from the economy and politics points of view. Although public health has taken an approach to this problem, it has been mainly disciplinary, since it has focused on the health effects of the unemployed and underemployed but it has failed to propose alternatives from the public policy to solve this problem. The purpose of this essay is to examine the unemployment as an economic, social and health problem of the population. According to records of diagnosis, we review this situation (which requires different strategies at various levels) including different groups involved and their organizations, the State, companies, trade unions and employers unions, not just people unemployed and underemployed.
