What kind of gray income does the property customer service supervisor have that does not violate the interests of the company?

Hello, as the property customer service supervisor, the service to the owner belongs to the work. It belongs to work, so there can be no gray income. However, if you are an employee of a property management company and don't serve the owner, when the owner pays you, it is considered as gray income that does not violate the interests of the company. But you have to use the company's platform, all the company's facilities and equipment, and related property. If you only occupy a little property, it is a gray income that infringes on the interests of the company.
