There is a certain breed of exec who is extremely generous with what they consider work. They will read a few articles after dinner and consider it "working all evening." Staying up late idly scrolling through LinkedIn is "working past midnight." Their accounts don't differentiate between operational work and social activities that relate to work. For example, wining and dining a stakeholder is always considered several hours of pure work. Once I worked with a CEO whose "80 hour" weeks included regular binge drinking and 2am kebabs with his buddies on the board.
