Owners openly vilify property personnel, can lawyers come forward?

If the insult is bad, you can call the police and ask for an apology.

If the property is performing its duties normally according to the rules and regulations, then if the owner's abuse is serious, it can be handled by the police on the spot. It is suggested not to have further conflict with the owner, not to take excessive actions, calmly handle the conflict and avoid indefensible. At the same time, do a good job in obtaining evidence such as audio and video recordings in case of emergency.
