Ah, yes, productivity. Whenever we spend a day at the office, we inevitably spend at least half an hour doing coffee/tea breaks, often more.
And in between coffee breaks, you’ll be wearing that headset and working with one another, as you do when at home, because management didn’t either miss out on the productivity boost to put people from different company locations into one team, if their expertise matches.
You may all be at ‘the’ office, but as soon as one person is at a different office, you’re all wearing headsets and might as well do so without a shitty commute.
