Consider, what the people on the production line are thinking about right now, finishing work, the fishing trip on the weekend, the necessity to get the car fixed and registered by next Monday, how can they pay that huge electricity bill, the game last night?
Think how much more productive it would be if they were thinking about how to do the job better, quicker, with less rejects, less risk of injury, to tighter more consistent specs?
And then consider weather or not it is a failure of the management culture that they are not doing so?
Googles 20% time, the famous 3M time, works for them, why not for everyone?
It is not easy to engage employees in this way, very few are able to do it, which is exactly why it is worth doing, as it delivers a huge advantage.
