When I was with the OPP (Ontario Provincial Police) as a communications officer (dispatcher) we worked 12 hour shifts. Our workstations could rise and lower as we wanted so we could stand or sit whenever we chose. It was invaluable in keeping us productive and awake. And it was super comfy for me as I am 6'5. All workstations should be made to be easy to reposition as either standing or sitting. These days I work for the feds and have a generic cubicle with static desk that is barely adequate and chair that doesn't go high enough. I wish I could stand at my computer now.
