I’ve only worked two places as big as OP described, but you probably see this more when your company leases a third of a floor on a giant office building. Or a floor and a half, or two half floors because it was easier to expand onto the 12th floor.
Elevators do back up, especially when everyone has to scan for their floor. Not like the author suggests, but you can lose a good few minutes a couple times a day that way. It does start some people on an exercise kick of using the stairwell to leave the building. Not great exercise though.
The one place solved this by not building parking garages. Flat parking that went to the horizon. By the time I got to work the spot I parked at was going to be over half a mile from my desk. I bought a grownup scooter with oversized wheels, first day I used it security tracked me down and said those aren’t allowed on company property (I had half a mind to use it on the sidewalks around the outside of the property but didn’t, since I’d still be carrying the stupid thing into the building). But I spent a lot on that scooter and had no other use for it, so I was mad.
My coworker had convinced me that this was billable hours (court precedent about a factory that had a bad setup for employees to get to the time clock) so I started phoning into standup when I was on site but still eight minutes from my desk.
When you’re walking half a mile to the security doors it tends to stagger the arrival times. Which is a feature, if the dumbest one.
