When I hired with the company I'm with right now, I negotiated a flex agreement, saying that every other Friday I'd have off. I have the email in which that was agreed to, and everybody's been happy with the agreement.
On Thursday, however, the boss with whom I negotiated that arrangement was let go. Because I've done a really good job, the old boss' supervisor would like to promote me to my old boss' slot. One problem, he says, however is that he's a little concerned about how I seem to be working from home "alot."
Upon hearing of the arrangement, he now "understands," but isn't sure if he can promote me under the current arrangement. What would be the best way to try to keep this flexible arrangement but still get promoted?
