These days every company is squeezed to cut costs. If there wasn't enough work to stay busy all day, I sure wouldn't advertise it by hanging out in a break room. It makes for an obvious target when it's time for layoffs. If the workforce for a particular department is busy only 75% of the time, to the beancounters, that means they can reduce the workers by 25% with little to no impact to operations. That's Business 101.
