Some jobs link compensation directly to work effort. Piece-work systems, whichpay workers for each bit of work they perform, are one example of this approach; soare contract workers (hired to perform a specific task, and paid only when that taskis completed). This strategy has limited application, however: usually employerswant their workers to be more flexible, performing a range of hard-to-specifyfunctions (rather than simply churning out a certain number of widgets per hour).
Both Kling and Stanford believe that there's very little between workers and their employers.
