Does your company promote the inefficient people? Perhaps it's been infiltrated by the CIA.

Or, more accurately, the CIA's predecessor, the OSS.

The OSS wanted a way to destabilize enemy production during World War II, so it created a classified guide entitled the "Simple Sabotage Field Manual."

In a masterful move, the head of the OSS, William J. "Will Bill" Donovan, declassified the document and made sure it was distributed. Why was this masterful? Yonatan Zungar:

What's particularly brilliant is that revealing these methods can be even more destructive than concealing them: consider what happens when every time someone does something stupid and inefficient, the response is for people to wonder if that person is actually a saboteur.

So what was in this manual? Here is one of several examples:

Managers and Supervisors: To lower morale and production, be pleasant to inefficient workers; give them undeserved promotions. Discriminate against efficient workers; complain unjustly about their work.

And you thought World War II ended in 1945. Obviously the battles are still being fought in some companies.
