I've found that I have a specific lifecycle in regular jobs. It goes like this:
1. Enthusiasm. No matter how many times I've gotten burned in other jobs, this one is going to be different! Management seems to be really open to improving things, or doing things as best as practically possible. Hurrah!
2. Passive-Aggressive apathy. Well, I was wrong. Again. Hells, this place moves slowly. No, management's plan or idea won't work, and I'll say so, but I don't feel like explaining it anymore because clearly they aren't interested in my opinion. I will slouch in my chair and grudgingly do what I'm told.
3. Complete apathy. I won't even bother to say that I disagree with their bad ideas anymore. Discussion is pointless; they simply want to do it their way, and that's that. I'll browse through the classified ads on my lunch break.
(Get new job, go back to 1.)
I don't think that particular lifecycle is unique to me. So, the author may be dealing with some folks that are completely disenchanted by their work environment, but for whatever reason they can't or won't find another job.
