mushroom management

1. Mushroom Management

Restrict employee access to information and decisions (keep them in the dark).
When information is conveyed, it is incomplete, inaccurate, or full of marketing hyperbole (throw shit on them).

Large, hierarchical, process-bound organizations are frequently guilty of the most egregious forms of "mushroom management."

shiiiiTAKE (mushrooms)

You use the phrase, "shiiiiTAKE (mushrooms)" where you might otherwise use the word, "shit"; such as if there are young children around or if you're on forums (or, "fora" if you want to be a dick about it) where the words shit and shittake are forbidden or censored (yes, a forum that I'm on censors the word shittake!!!).

{in a room where a toddler is present}: Gosh I don't want to go; I feel like shiiiiTAKE (mushrooms) this morning.
