I'd be curious to know whether Sheryl Sandberg's staff are also allowed to leave at 5:30. Or is this just a privilege available to a senior executive, which she might never even consider granting to her underlings? I'd be more impressed to hear that software developers at Facebook could work the same hours. Anyone at Facebook have any insights on this?
I don't know about staff closer to Sheryl (ie, not in e), but there are definitely many software and other engineers working 40-45 hours a week fairly standardly, and I seemingly don't hear enough negative chatter about it for me to recall hearing any.
