That's a good point about detaching. I hadn't thought about it that way before. He's an intelligent and caring person. Terribly impractical though even in his personal life and I believe has always felt a bit lost and looking for acceptance (probably those feelings fueled his desire to go into counselling so that he can help other people not feel that way). Even as his friend, I can say he is absolutely frustrating at times (I think mostly due to having a preponderance of Fi values that are important to him, but make daily living somewhat laborious and him very inflexible in those respects) and I can understand how a Te dom admin (which many principals are) would be rubbed very wrong by that alone, let alone the Fi outbursts.
I think the problem is exaccerbated by the fact that he has primarily worked in situations that do not attract a lot of steady and proactive admin: inner city or poverty stricken/isolated/dysfunctional reserve communities. Even the best of people would find themselves sucked dry rather quickly, and often they are not starting out with admin who even at the beginning are trying to change the system or be proactive. At the same time, those situations provide a larger than average population of needy students (life or death issues), a lot of judgement calls that could go wrong if politics and community members and school policy are not all balanced and taken into account, etc. There's a lot there that would trigger righteous Fi anger. Directed appropriately, I think that kind of fuel could make a big difference. I'm worried for him though, as he is being hired to co-administrate because these issues come to the forefront even more. He is not only going to be a VP, but is the resource person who will work with the most academically/behaviourally deficient kids in the school.
EDIT: Someone asked about whether he is part of a union etc. The answer is yes. In this particular case, the school is under the umbrella of the provincial school system, which would allow him to be under the provincial teacher's union. The school however, is under local control by the native population (which is usually a dicey situation due to the factors that are influenced by living within a small community of people who are mostly interrelated. In an attempt to rush self-government, often unqualified people are put into positions they are not prepared for and they focus on minutia or want to turn a blind eye to problems involving their relatives, rather than tackling the issues at hand). The community can only be accessed by plane and has less than 1000 people in it.
In the past, he has been in the provincial teacher's union, with the exception of one bandrun school which he was employed at for only a few months while he was still collecting his payout from the previous job.
