The announcement by Twitter recently that they are embracing remote work going forward didn't just happen:
“We’ve already been on this path, and the crisis just catapulted us into a future state. [I believe] flexibility for workers is the “fourth industrial revolution" because it will fundamentally change the way people work. The future of work is offering employees more optionality.” - Jennifer Christie, Vice President, People at Twitter
(Quote source The Washington Post: Americans might never come back to the office, and Twitter is leading the charge)
Important: They had been planning this for two years. Successful remote work environments do not just happen. They require careful planning and design.
