Sometime ago I heard an story about a Firestone plant in Puebla, Mexico.
They needed a lot of production, so they gave really big salaries to its operators (from 500 pesos a week, they raised to 2,000) hoping it would be an incentive.
It worked the other way: Once the operators got their 500 pesos by working 2 or 3 days, they just didn't care of working the rest of the week and the absentism throw production down until the plant was closed.
So there's a lot of people who just doesn't care about being ignorant. They like that way.
I think that Open-book management only can work for companies full of well educated, responsibles, intelligent employees... and only the small companies with few employees can reunite such quality workforce.
