When I was doing contract work, I worked from home (Denver) with people in London. I'm an early morning person, so I would start work at 6:00 am, and I had plenty of time to communicate with people in London before they closed for the day.

I loved working at home - no distractions. I could stay focused for 8 straight hours, and I did not need social time.

Now I work in an office that has been broken into 5 cubicles. I really dislike having to hear other people's personal phone calls! I use headphones when I have to, but I prefer to work in silence over background sound of any sort.

I think working from home and working with people in different time zones are really two separate situations. I wish I could work from home now - just one day a week! The team I am in has proposed this multiple times, and we have been denied and warned not to bring it up again.
