Industrial sickness refers to a situation where an industrial firm performs poorly and incurs losses for several years, defaulting on debt repayments. A sick unit fails to generate profits continuously and depends on external funds. Signs of sickness include short-term liquidity issues, revenue losses, operating losses, and overuse of credit. Sickness is caused by both internal factors like poor management and technical issues, as well as external factors such as infrastructure problems, government policies, and market constraints. It is a growing socio-economic problem impacting employees, investors, and the economy.
