I don't think this is a reflection on performance. seems like the key word here is "obligated" to work after hours. this is due to managers pushing deadlines on their reports. honestly this isn't much of a surprise. If your boss is obligating you to work after hours you are unhappy. one issue here asking engineers to work after hours in a 'you build it you own it' culture. in my mind this qualifies for being "obligated" to work outside of business hours.

A more interesting item in the slide deck is that anyone that has more than 2 hours of meetings in a day has a loss of focus. I think it's conceivable to say that a heavy meeting culture may also force people to be "obligated" to work after hours because they have lost focus time in the day.
