My employer is a huge fan of WFH and it's the only arrangement I've had in the 18 months I've been here. I personally don't really care for it all that much. I sit at home everyday all day save for going out for lunch most days. My team never gets together and there's alot of mising "connection" if you ask me by only working via phone/email/IM.

The other downside is that the "office" I have built is right at home, so I can sit down at any hour and talk to people, and I often do sit here at night talking to my team in India when they come in.
