That sounds like a bug to me. If there isn't already a report about it on AHQ you should start one. If it turns out it's an intentional "feature", or if you are doing something wrong in the steps, Crinrict or one of the other helpers usually lets you know pretty quickly.
Edit - Sorry, I missed the part where you said you had already posted it. Hopefully you get a response soon. It definitely sounds like a bug though. Taking the "family leave" option should prevent the go to work trigger. They probably just forgot to include the "work from home" notification in that.
I don't have anyone pregnant right now, but I can try to mess around with it this weekend, and see if I get the same problem happening. Do you have a link for the AHQ post that you made?
