Should the security guards of property companies be liable for the accidental injuries of factory employees?

Theoretically, the injured employee was injured in the factory, which belongs to the category of work-related injuries. His medical expenses should be divided into three parts, most of which should be borne by industrial injury insurance, some by medical insurance and the rest by individuals. What you need to compensate is the third part, that is, the medical expenses borne by the injured employees. And this part should be borne by the property company where you work first.

From what you said, both you and the injured employee are shirking their responsibilities. The factory doesn't want to bear the responsibility for work-related injuries, and the property management company also wants to avoid the liability for compensation.

I suggest you negotiate with the injured employees, report and complain to the labor inspection department about their respective work enterprises, and seek judicial support. The urgent task should be to cooperate with injured employees to identify work-related injuries.
