The context switch is what you make it. My switch is a daily ritual whereby I sit in a specific place and read for an hour with a little background music and a drink (if so inclined). That symbolically “closes the door” to the office, even though my flat isn’t big enough for separate work/rest spaces.
As a long time Amazon employee, disagree and commit essentially works like this:
Employee: “I’m not convinced this is the best way to do something”
Manager: “Noted, now stfu and do what I say”
