In my opinion, you should speak with the management to understand their stance and/or concerns. This can be done formally or informally but I would prefer informally just so they won't have their guard up, preparing to say 'no' to you. After you've understood their needs and concerns, as someone else has already mentioned, clearly defined your value proposition to the management team. Provide some structure/insight into the plan on how it may work, get some research supporting remote working and how it has made a tremendous impact on organizations in terms of creativity and boosting the bottom line. Offer to do a small pilot test if the situation allows for it. It's a negotiation situation and when you're clear about the other party's interests and concerns, you'll know what's stopping to other party from saying yes. Good luck! I for one enjoyed remote work in the past but probably because I live far out and don't have kids, I find that going into office to see some faces and talking about tech stuff is more fulfilling. That said, who knows how I would feel further down the road.
