When I listen to my company's upper management I get the impression they genuinely believe that everybody spends mopst of their time in meetings and discussions and then sometimes does some deep work. They seem to have forgotten that the lower ranks spend most of their time on doing actual work and that distractions and interruptions there are quite expensive and unproductive. What's often weird is that they also set up the workspace in a way that collaboration is hard because when you talk to each you might bother the people in the next row.
