Sounds like you're thinking of isolated robotic workers.

An ideal worker in my mind has many human qualities that make them enjoyable and inspiring to be around. They make other employees happier to come to work and help them be more effective at work.

Granted, it's a lot easier to measure that Tom produces 15% more widgets per hour than it is to tell that Cindy's presence increased the entire factory's output by 5%. But still, the latter provides more value to a company so I expect improvements in evaluating that.
