Yes men

[Little_Girl]

Men without balls who will answer yes to any query from their boss/superior regardless of the questions intelligence, bearing, or appropriateness. It is usually intended to farther the yes mans carreer by getting and staying on the bosss good side, but may have the opposite effect.
Yes men often ruin the productivity or usefulness in the department they work in, as they are unwilling to provide any form of original idea, opinion or more importantly criticism to their boss and thus contribute to disconnect between managers and workers.
