Library post! Incredibly bad management at local library system

TBO has been a library branch manager for a couple of years now, and has done a great job at her location, by any and all measurements. A couple weeks ago, she found out that she was being moved out of her branch and placed into a high stress situation at a smaller and less well-suited site. Sounds pretty much like a demotion or maybe just a stupid decision, doesn't it? (I won't even get into the fact that TBO is 7 months pregnant!) What was the reason for the change? Someone else--with less seniority, mind you--put in for a transfer to her occupied position. This librarian--I'll call him Dick--apparently was having a personality conflict with one of his subordinates, and instead of handling it like a manager and documenting insubordinate acts, counseling the subordinate, and otherwise doing his freaking job, held his bosses hostage by threatening to sue the city for God only knows what, because anyone with half a brain would realize he has absolutely no grounds for any kind of lawsuit. His bosses (who clearly lack even that minimal capacity of brain power) caved to Dick's craven demands, moving TBO (and a number of other people), causing her (and the others) to suffer needless dislocations of their lives and careers. TBO is massively upset by this, especially since the branch to which she is now assigned is a time bomb of unruly after-school occasional delinquents.
Dick now claims complete innocence in all of this, maintaining that, "Gee, all I did was submit a request. I didn't cause this!" Uh huh. Let's think about Dick's other options:
1) STFU. (I don't really blame him for not doing this, but it does have the benefit of screwing over the fewest number of people, and the correct person gets shafted.)
2) Request that the subordinate be moved, abdicating all managerial responsibility. (The fact that Dick didn't choose this option belies his innocent claim that he didn't specifically request to displace TBO, displaying for all the world to see both his disingenuity and his total lack of concern for his fellow co-workers. It also has the objective appeal that only one person is affected.)
3) Be an actual manager and handle your personal/personnel problem professionally. (Obviously Dick wasn't a good enough person or manager to do that.)
So, now all these fine innocents have to uproot their patterns and lives to accommodate one useless scumbag. Seems like the bosses would have thought about that before acquiescing to Dick's extortion, huh? I guess Dick isn't the only incompetent . . .

*I know this term can be offensive. This is why I'm using it. I am in no way making light of or denigrating penises. Except for Dick, that is.
