The OSS has some helpful hints (see section 11a on page 28):

(for anyone who hasn't seen it, in WWII the OSS came up with a pamphlet with suggestions for how workers in occupied Europe could discreetly sabotage war production. Much of it is 'blue collar' sabotage - run your drill press too fast (wears out tooling prematurely) or too slow (fewer parts per hour), sand in the crankcase, etc, etc. But one section is for the white collar folks ... and their hints on how to sabotage things will be all too familiar to anyone who has worked in a large bureaucracy.
I was not a good bureaucrat ... I had am image of that page framed on my office wall.)
