I get lots of work traffic on my cell phone. So ya, email, desk phone, cell phone are part of my work protocols.
It's part of communication and being responsive to your customers.
Why the hell not.
And this is a bad thing how?
I hate bright florescent lights. I'm the guy that gets up on a ladder and gives the tubes a 1/4 turn twist to shut them off.
(I also use dark mode for everything, like the overhead lights it's easier on the eyes so less strain over the course of the work day.)
I don't where my Air Pods to talk on the phone all day. Usually they are there for:
#1 Low background music to enhance concretion by eliminating/reducing external distractions, or
#2 No music playing and simply used for Noise Cancellation to provide a quieter work environment.
And going into his office with the lights on and the door closed would be different?
