My boss is having an affair.

My boss is having an affair with someone else at work, the whole office knows. She’s married, he’s not. They’ll go into each others office and spend a ridiculous amount of time together and leave looking giddy and flustered.

Now here’s the kicker and dilemma… Her husband regularly comes into the workplace. Minimum once a week to take her out for lunch or pick her up etc. I feel terrible having small talk looking into his eyes when I know what’s going on.

Should I say something? Is it my place to say something? I’m scared of the consequences that would probably result in me getting fired but feel guilty. Very guilty.
