Well just have enough people employed, it is not about the quantity but the quality of work that is delivered. Here they say if the work load is too much the quality will suffer under it. An other aspect is that family time is also very important. Though Holland is a very small country they are fourth country in the world in export and have some well known companies like ING, Heineken, Unilever, Philips, Shell..
So it does work if you just work between like 35 and 40 hours a week. Just about planning.
