Why are middle-aged and elderly sanitation workers now required to buy insurance?

Requiring sanitation workers to buy insurance is a great thing that benefits the country and the people, and sanitation workers themselves benefit from it. Due to the large traffic volume and high speed of vehicles in cities now, sanitation workers have become a high-risk occupation, and workers who go out to sweep streets in the early morning are even more dangerous. Especially among front-line sanitation workers, 70% are laid-off workers and temporary workers with financial difficulties. Once an injury accident occurs, it will be unbearable for their families. Sanitation workers buy insurance to solve their worries.
