Agree about "work from home fatigue". Many people I know, especially in Asian countries cannot strike balance right too, completely abandoning family life even staying at home 24/7, as their bosses know very well that they are in front of their PCs or 10 meters away from it at most, so can ask anything, anytime. No more unsocial hours for them. Just had the same conversation yesterday with my Singaporean office. They are dying to get back to the office space and draw the line between office and home.
Another discussion I had with Bloomberg employee. Many members of his team are EU citizens and they have quietly relocated back to Cyprus, France, Spain, etc, you name it, abandoning their London flats and basically not informing Bloomberg. Of course weather is better, expenses are less, etc. But bosses of Bloomberg are now furious and want everybody back to London as soon as possible for various reasons, one being residence status implications.
