Can the property security guard directly let him work for 8 hours if he disobeys?

I can't. Security guards are hotel employees. They have the responsibility and obligation to protect the safety of property. They must abide by the rules and regulations of the property, obey the management of the property, and abide by laws, regulations and administrative rules. There must be no violations. If the security guard is disobedient, the property can deal with him according to the prescribed procedures, but he can't stay for 8 hours directly, because it doesn't conform to laws, regulations and ethics. In addition, the property can also take other measures, such as training, rewards and punishments, to correct the bad behavior of security guards, so that they can better perform their duties and protect the safety of the property.
