Obviously the causation can’t be explained here, but there is unsurprisingly a correlation between employee happiness and company performance.

The question then becomes: does a company with happy employees perform better, or do better-performing companies treat their workers better?

The question of "pride" in relation to the employee/employer relationship comes up a lot in internal surveys, in my experience. This paper seems to seek to take a fairly technical approach to understanding the importance and impact.

It does raise the more general question though: what does it really mean to be proud of your employer?
