It's broader than productivity alone. A team that's working long hours can be perceived as more committed, dedicated and in a fighting mood.
It's really all about team dynamics and corporate culture.
See, successful entrepreneurs are, more often than not, binary beings that totally devote themselves to their company and expect other the other people in the team to do so as well.
Someone can come and work for 5 hours and accomplish just the same as he would over 11 hours but it may send the wrong message to the group - that the company is secondary to personal life and that just meeting your obligations is really enough, no need to do beyond that.
Furthermore, some people wouldn't be able to accomplish the same over a short working day; how would that make them feel spending 11 hour days in the office, while their colleague leaves after 6 hours and still gets appreciated?
