The company didn't buy social security, and I broke my bone at work. What should I do?

First of all, the unit did not buy social security. As long as you have sufficient evidence to prove that this unit is illegal. You can report to the relevant labor department (labor bureau, social security department), provided that you have evidence to prove it.

Secondly, the unit should be responsible for the fall and fracture during work, which is a work-related injury. However, there are two situations: 1, the company bought social security, and part of the work-related injury expenses were paid by the social security fund and part by the company; 2. The unit didn't buy social security, and all the expense units were responsible.

Friends, take up legal weapons and safeguard your legitimate rights and interests. Good luck!
