I think I've been very lucky in that I've been a permanent work-from-home engineer for years no. First our customer decided it wasn't so important that we work on site at their office and told us to go to our warehouse 10 miles away instead. Then my manager and coworkers all moved away and I was transferred to a team that already was mostly work-from-home, and manager at the time told me it was fine to work from home all the time. Now it's down to only a few times a year that I go to the Bay Area, mainly due to non-work commitments and because my work computer seems to like to connect to the company network in the office now and then to make it happy. It's been a great thing for me, and I hope that they don't ever decide something like, "We'd rather have all of our engineers in one building" again.
