Mushroom Treatment 

A term that draws it's history from the United States Military, particularly the combat arms. It refers to a management concept adopted either accidentally or on purpose by shitty leaders. This leadership style is defined by being light on details and withholding information. Concurrently shitty leaders will ensure that the information that does get passed along is either incorrect or unreliable (See Bullshit)

Lit:
Keeping subordinates in the dark and feeding them shit.

Ex:

Bob: Hey bob, do we know the plan?
Dave: No Dave, we're still getting the mushroom treatment, we'll probably figure that shit out when it's too late to do anything about it.
