Amazon is building HQ2 somewhere, Google may build a new campus in San Jose. There is a lot of talk of traffic and side effects of these large campus. For leading tech companies wouldn't working remotely be a solution? What happened to all this work anytime from anywhere Nirvana of the 21st Century?
The official Amazon answer is it's up to each team to organize itself how it wants to. However 99% of teams won't do this. Amazon culture believes in two pizza teams collocated. But it's not a company rule. Working from home a couple days a week is totally doable in a lot of teams. I thought about buying a vacation home about 2hrs from Seattle and working from there Mondays and Fridays, or Thursdays and Fridays, and renting a bedroom in the city for three days a week. I think that would totally work. But for most orgs you'd want at least a couple days a week in the office to stay connected.
Many managers at Twitch, an Amazon subsidiary, allows employee to WFH 1 to 2 days a week..
Regularly work for 2-3 days per week from home at Amazon.
Good luck trying to use academic research and good judgement to convince those companies that remote work is good for employee productivity, happiness and morale. Gooooood luck.
