Mushroom Management
"Mushroom Management" is an allusion to a company's staff being treated like mushrooms: kept in the dark, fed a steady diet of bovine manure, and -- when grown big enough -- canned. The connotation is that the management is making decisions without consulting the staff affected by those decisions -– and possibly not even informing the staff until well after such decisions are made.
This phenomenon is an anti-pattern most commonly found in organizations which have a strict hierarchy and barriers to cross-organizational communication -- especially those with a stovepipe organizational structure, such as the military -- but can be found in any organization.
Negative Selection
Negative selection, in politics, is a process that occurs in rigid hierarchies, most notably dictatorships.
The person on the top of the hierarchy, wishing to remain in power forever, chooses his associates with the prime criterion of incompetence -- they must not be competent enough to remove him from power. The associates do the same with those below them in the hierarchy, and the hierarchy is progressively filled with more increasingly incompetent people as the hierarchy declines in rank.
If the dictator sees that he is threatened nonetheless, he will remove those that threaten him from their positions -- "purge" the hierarchy. Emptied positions in the hierarchy are normally filled with people from below -- those who were less competent than their previous masters. So, over the course of time, the hierarchy becomes less and less effective. As this happens relatively often, once the dictator dies, or is removed by some external influence, what remains is a grossly ineffective hierarchy.
Seagull Management
Seagulls are known for swooping down unexpectedly, squawking loudly, taking whatever they want, and crapping all over everything else as they fly away.
Persons who practice a form of "Seagull Management" will show up unexpectedly, shout their demands, take anything they want, and threaten people with job termination as they leave.
