Little Big Workshop

Getting this is pretty simple, just don't enough breakroom to go around. Doing this in the middle of a playthrough might not be the best idea though and is easiest to do from the start of the game. To make this as easy as possible, start up a new game and skip the tutorial by pressing start and selecting the appropriate option. (Netting you Too Cool for School if you don't have it already) Then, immediately hire 3 more workers, buy some workstations, and start up a big job without a breakroom. If you set it to the fastest speed you will get this within a minute.
