Deming knew how to do it, and even outlined that the entire economy would rise because of improved management practices. I very much believe he is correct.
Child: Daddy, will you play wit me?
Dad: Sorry, I can't I have things to finish off from work.
Child: Why don't you do it when you're at work?
I did the same thing at SAIC when I had a private office. Then my motivation was to have an hour or two for uninterrupted coding.
Except for 2013 I have worked remotely from home, which can be very good, but I do miss out on face time.
I am a weirdly fluctuating person and some days I work best in total seclusion. Others I need to sit in the middle of a cafe and have the noise and people around me.
So my goal is to be as adaptive as possible without harming the day-to-day work life.
Yes, at (former, thankfully) employer its the border between actionable offense (being written up) and merely being viciously trashed at review time. Management made the explicit decision to enforce collaboration (a 'la the whippings will continue until morale improves) and your actions are direct and intentional insubordination of that explicit formal requirement.
One person will get yelled at in front of everyone else (because its open office, duh) and nobody will dare to wear headphones again.
Its hard to find a more open and shut case description of intentional willful trivially documentable insubordination.
