The company I work for now, Opsware Inc, is headquartered in Sunnyvale CA. We have offices in Redmond WA, Cary NC, and overseas in London and Brisbane.
One of the handy things about my current role in the company, ie one of providing phone and email technical support to our customers, is that as long as I can be on the phone, I can work from almost anywhere. Typically I can’t work from home, which would be very handy, but I can work from Sunnyvale, rather than my normal Cary digs.
The past two weeks, I’ve been in San Francisco on vacation. However, I didn’t want to take any time off from work, so I arranged to work from the Sunnyvale office while I was out here.
So, it’s not quite WFH, but it’s a close-ish substitute.
