Lacking in literate on the subject of informal sector, especially on its prevalence, potential contributions to the national economy, changing faces in the light of current economic trends, among others, makes the formulation of a holistic intervention for workers under this sector a seemingly impossible task.

Thus, this paper is aimed at eliciting baseline information on the working conditions, and occupational hazards and risks confronting selected groups of Filipino informal sector workers.  Information derived from this paper may aid in policy formulation and information dissemination toward promoting improved working conditions and occupational safety and health for the informal sector workers.
