All-hands conference call
The notion that gathering 17 people around the world to stop what they're doing and listen to someone run through a spreadsheet for an hour and a half is in some way a sensible idea.
The worst kind of conference call, with countless participants, redundantly representing all different walks of departmental life, each to donate an hour of their sorry existence in deference of the great dogma and the cast iron guarantee that nothing will be achieved beyond ratcheting the tedium and entropy in the organisation ever nearer that threshold of boredom heat death at which point all our trials will be over, the great day of judgement will be upon us, and we will at last be delivered from our suffering.
