This is a vibes based argument though. I can make similar claims about how improved worker satisfaction will lead them to work harder, make less mistakes on the line, boost morale and have a multiplied effect on productivity as they not only work better themselves but the entire team works better if they're happier. There are even some studies to back up these claims, so I was just curious if there's evidence to the contrary.
