No, absolutely not. Hmm. Let me rephrase... HELL NO, NEVER IN A MILLION YEARS!

Sorry, I in no way mean to expressing anything negative about you in any respect Jennifer, but this is a really, really bad idea.

First, work is work and home is home. Neither should cross into the other, as a general rule. By doing this, you are giving up power over the knowledge. That power then falls to your subordinate, and the chances of this information falling into the wrong hands just went up by A LOT. Further, as others have noted, the dynamic of you being this person's supervisor just makes this wrong. Worse, if your revelation of this to her gets to HR you could be looking at harassment issues. This just isn't something you discuss with coworkers...ever.

I also agree with Sandi; there's minimal reward to be had from this. The risks are enormous. Not only could you lose your job, you might not be able to get a similar job once a potential employer inquires. As Jasmine noted, the fallout here could be tremendous and affect your marriage.

Telling your subordinate has absolute disaster written all over it.
