I find it funny that a nearly identical comment (different wording, but ssame joke and no follow-up) in this thread hasn't been receiving the same negative attention.
From the article:
> an individual subscribed to the calendars of a wide range of employees outside of their work group.
Following your manager's calendar makes sense. Doing the same for people outside of your group is suspicious imo, unless you're working with that team/person.
I think the word "tonality" is used liberally in this article. They didn't seem to be referencing any specific style of harmony, but rather the general act of using distinct tones to create music.
