impedership
n.— «A large percentage of the time, the team accomplishes less than it might have in the absence of management—that isn’t “leadership,” rather, its opposite. We need a new word for that, and because such management impedes progress, that word logically would be “impedership.”» —“A new word for the old boss: impedership” by Dale Dauten Boston Globe Feb. 4, 2007.
