Maybe it's my audio setup, but I've tried multiple types of headphones to no avail. I feel the quality of my work (and life) would improve if I could cope better with calls, but despite my efforts, I can't do it. I've removed myself from calls with an adjacent team that mostly don't concern me, and asked them to ping me only if they need me. That saved 30m to 2 hours of my life and saved me from becoming exhausted before the day has properly begun.
There's also a problem in that _some_ people prefer WFH because they can slack off more (or have multiple jobs); that means they're not always available and not fully committed, with whatever implications for the people who rely on them and the company/product.
Maybe it's down to the pace of the work. Startups, I feel, benefit from in office huddling. Corporations with ample time on their hands could be better suited to WFH.
