The belief that grunts (like the hard working grunt) aren't paid enough might not be sufficient on its own to make the end result (people getting mad at that grunt) believable.
But what if one considers it as one of several beliefs frequently held together? What if a grunt believes the following?
A) grunts (in general, but also including the hard worker) don't get paid enough for how much they work
B) grunts have more control over how hard they work than over how much they are paid
C) if one grunt works extra hard, management will start expecting all grunts to work that hard (exacerbating what they already think is a poor work/pay ratio; see A)

Now is it a stretch?
