Can the property staff help the owners collect fees?

Whether to charge for private behavior is up to the parties themselves.

It is a private job for the property staff to help the owners collect fees during working hours, and the company can pursue individual labor discipline.

If the owner asks the property staff to provide additional services as a property company, they can charge.

In the property industry, this is called "special service", and you can charge corresponding fees (according to the regulations of the property association, there are specific subjects and unit prices)

The usual service varies from 5-20 yuan per hour, excluding the cost of tools and materials.
