Tenant unemployed but didn’t tell me yet

[Kurt S.]

Hi,

I am living in a duplex as the landlord with tenants (a couple) living in the unit below.

The mailman mistakenly delivered a letter from my tenant to me today. Sadly it is from the office of unemployment.

I live in a tenant-friendly city. I thought they were obligated to tell me in writing.

Am I legally allowed to confront them about the situation? It’s not clear it will be any immediate threat to their ability to pay rent. His girlfriend had the better credit of the two to begin with. However I am obviously worried, as my bills depend on their ability to pay as well. Any advice?
