The western civilizations, especially the USA, are deeply influenced by the ideas of Calvinism and Puritanism, it is influenced by a work ethos that says work hard and think about that you will get the benefit into the future (heaven). Most people and managers still believe that you have to work not only heard but also long to get more done.
The interesting thing is – that believe is wrong! Since more than 30 years people in the manufacturing industry know that the performance of assembly line workers goes down after the 6th working hour at a day.

Both articles show that we do need to stop with the idea that Software Development Teams shall do overtime! It is clearly unproductive!
Work less equals to more productivity.
