Thought about this but it should be a self-regulating system to some extent. The longer a task takes, the higher its value. If it becomes overvalued (workers are deliberately doing it slowly and making less money than they could, which is questionable), then it becomes more attractive to workers who will complete it faster.

MM ever worked in a traditional factory type setting? all the workers collectively do this and if you not you would get sent to Coventry.

And this is tame compared to what used to happen back in the 70's in engineering "go slows" and backhanders paid in brown paper envelopes - I was told "even the tea boy got £900" about a 1/3 of the average wage at the time.
