I would like to point out its not even we. Its upper management and 'the stockholders'. Everyone from the peon to lower management knows that people don't work continuously for their shift. I doubt anyone can work continuously for that long and not go crazy.
But the reward from mid and management and above for completing your work is more work. Which is great for them since you completing more work means they get bonuses.
To be fair, I did have a watch that automatically synced itself to the us naval observatories atomic clocks over the air.
