This book focuses on the core problems of occupational health, safety and well-being of workers in the informal sector in developing countries, where it accounts for most of the rural labour force and a substantial percentage of the urban labour force. The sector is characterised by low incomes, unstable employment and lack of protection in the form of legislation/policies or trade unions. Though some health and problem-solving measures have been introduced, a focused academic effort to address the problems confronting workers in the unorganised sector, or informal economy, is lacking. The book evaluates workers' physical and mental health in the context of labour migration, social inclusion of minorities and the differently abled, provisions for women workers, demonetisation, occupational safety for hazardous work, and in connection with various areas of informal work, e.g. agriculture, construction, transportation, sanitation, tanning, the tobacco industry, powerloom industry, surrogacy, and self-employment. It provides a well-rounded description of an analytical reflection on the challenges these workers face and focuses on social policy changes to help alleviate them. Accordingly, it offers a valuable asset for researchers and students interested in development studies, the sociology of work, health and labour economics, public health, and social work.
