Help Wanted

A racketeer sets up an employment agency, and then sends his henchmen to lineup foremen in companies that employ unskilled labor. The foreman is promised a cut on each new man he hires, and the agency gets a whooping percentage of the new employee's first month wages. The foremen then fire the last new-hires and then another batch of new-hires goes through the cycle. And another after a month. (imdb)
