There was a nice story circulating at a previous place I worked (medium-sized American multinational).
It concerned a young German woman who came for a job interview. Naturally, her interviewers mentioned unpaid overtime sometimes being required, showing "commitment", etc. etc. How did she feel about this?
Her reply? : "In my experience, if a company is properly run then this is not necessary".
BTW, the lack of correlation between long hours and productivity has been officially known about since at least the First World War, when studies were done on munitions workers. But yet the myth persists...
