Working from home has made me realize that my company's mandatory in-office days are more about managers wanting to see us than about productivity. I've measured my own output and found I get 30% more done when I'm not commuting and dealing with open-office noise. But I also miss the spontaneous brainstorming that happens in person, which rarely occurs in Zoom calls. So is the five-day office week really necessary for collaboration, or is it just an outdated control mechanism?
