Executives are often always working as the job can be demanding, but I think it is a real step backwards to make that the culture of the whole company. People need to be able to live their private lives, outside of working. And in creative work, productivity won’t increase with more hours - at best you can pull off a short term increase like if you’re getting ready to ship something. But beyond that, it’s counterproductive and naive leaders may end up rewarding people who make their extra hours visible over people who actually add value.
