Is it public liability insurance if the property management company arranges cleaning elder sister to go to the owner's house to do housework and get injured?

The cleaner belongs to the property management company, and his injury has nothing to do with public liability insurance.

If the cleaning business is undertaken by the property company, the cleaning staff who do housework belong to the company. The injury should be a work-related injury and should be treated as a work-related injury, and then the property company and the owner should negotiate compensation. If the housekeeping is undertaken by the cleaning workers themselves and is not a work-related injury, the cleaning workers should negotiate compensation with the owners.

Public liability insurance is a third-party liability insurance related to the management responsibility of property companies. Its definition is: the property company should be liable for compensation in the process of implementing management services for the public parts of the community. The two cannot be confused.
