Can the property company undertake the security assignment business alone? For example, is it legal for a school to hire a property company security guard to be in charge of the guard?

You should belong to labor dispatch, and the property management company charges a certain percentage of fees.

Legally, property management companies can send labor services.

However, if the wages of your dispatched employees are also included in the labor cost of property management fees, they should be included in the paid service cost in financial accounting. Then you are illegal.
