Office Meetings Are Most Useful to the Least Productive Workers
When the creator of Dilbert died he left behind him some literature he had composed, not just lots of invaluable cartoons based on his life's experience (he was married with children before the Dilbert era; he experienced "office life" and his comic strip reflected on his experiences).
In my "office life" days I really didn't like meetings; it's not just that those were typically boring and fruitless, the hardest part was trying to actually not fall asleep (literally!) in the room or to somehow hide the fact you're falling asleep (staging it being the mere hiding of one's eyes, not involuntary naps). Another annoying thing about meetings is that, given they have a set time, one has to keep both eyes and mind on the clock; it makes it hard to concentrate or maintain a train of thought. For some jobs, this is destructive. Many bosses underestimate just how ruinous that can be to one's productivity - the very existence of some imminent meetings is a mental yoke, which should ideally be avoided (but under-productive bosses don't want spontaneous meetings, they have their precious "DIARY" or "CALENDAR!).
In hindsight, having no more meetings helped me be focused and efficient. And think what you will about the creator of Dilbert, the comic strips were brilliant and oftentimes hit the nail on the head. █
