He told the HR manager that I have been harassing him online and making threatening and violent comments against him.

They crack down on the compliant landlords they can harass to comply with various minutiae and get their numbers up.

And because they have the permission of the owner/developer they are not harassed by the city.

Please comment, message, harass me!

The tenant called me and verbally harassed me.

Many SRO tenants, particularly in cities like Chicago, New York, and San Francisco, are protected by laws that prevent harassment to vacate the property.

I then considered that I don't want to do it without speaking to my attorney in case there are any harassment laws I could be tripping over. 

Hello BP,I've got a tenant harassment problem and I'd like to know how you would handle this situation. 

LL carry things too far too often, thinking they need to control the aspects of a tenant's life, need to keep their concerns confined to the property, not so much to the people, that becomes discrimination and/or harassment. :)

Would you consider a landlord calling a tenant once or twice a month who never answers or communicates in any way who is several months behind on rent to be harassment by the landlord?
