Does the Regulations on the Administration of Security Services work? Do the internal regulations of the property company have to be observed? What will happen if they don't?

Of course it works. The losses in the security work shall be compensated by the unit, and the property management company shall not stipulate that the security guards shall fully compensate. Property companies can only formulate internal management reward and punishment system, which must be reasonable. It's definitely unreasonable for the security guard to pay for everything.

Article 46 Interpretation: If a security guard participates in or takes advantage of his position to cause the above situation, he must be investigated for responsibility.
