Seth: you're being offered the option to do your existing job from home? Or is this a new job?
One problem with working from home is that you have to consciously draw the line between work and not-work every day, because you don't have an easily differentiable “place of work”. I suspect that would be a problem for me, but maybe not for you. Still, keep it in mind.
I was having my weekly-ish informal get-together with my manager and then he said, “Oh yeah, close the door for a minute, I have some confidential stuff to talk about.” As soon as he mentioned that our department will be reorganizing in some fashion in the next months, I was pretty sure I knew where he was going, and I was right: he wanted to know whether I'd be interested in a managerial and/or supervisory role when the time comes. Damn straight! The great irony is I'm still not a member of CWRU staff quite yet, but my department finally finished going through all the resumes and coming up with technical shortcomings for each of them, which should sufficiently mollify HR.
