>That's only true if you didn't read the next two sentences.
I understood it well. What we both agree on is that it will make them feel bad. What we disagree on is this statement of yours:
>This will tend to make them more interested in leaving the company.
Now I don't want to claim 0 correlation. There sometimes is a weak correlation. There is also often a negative correlation (they'll stay longer at Facebook with guilt tripping than with no peer pressure at all). I'm not an academic, so I don't have the studies at hand.
>I'm sure guilt and shame don't work well in negotiations. I don't know whether that translates to shaping society or influencing your friends.
It's a fallacy to treat negotiations as distinct from friendship. I think you're confusing bargaining with negotiations. You engage in negotiations with almost every person you interact with - friends, spouses, children, parents, coworkers, charities, etc. Want to have dinner with a friend? When and where? That's a negotiation. An ordinary person will negotiate a few times a week at a minimum. The discipline of negotiations encompass these interactions.
Negotiations courses/books often spend time on how your negotiation strategy will impact your relationship with the other person, and which strategies may help or harm the relationship. They don't suggest one never use guilt tripping - they merely suggest not to use it if you want to maintain a relationship with the other person.
