Way too many people enable way too many notifications on all sorts of platforms, which is admittedly the default. (And way too many people expect people to always be instantly available when they send a message/chat/email/phone call.) I'm actually pretty reachable during the workday. But maybe because I worked for the first part of my career in a world where I wasn't reachable if I wasn't sitting at my desk, I'm not terribly sympathetic to those who feel they need to reach me instantly.
