Not really data in any sense justifying the plural use of the word, merely a look down the hallway of the chair where I work – nobody comes in before 8:30 and most people have left by 18:30, averaging a nice-ish 40h/week, given that those who come in early will leave early, too, there are extensive lunch and coffee breaks and most people keep their evenings and weekends work-free (though, of course, not all of them).
