It looks like that study shows that the median CEO works 50 hours per week, with 10 of that spent in travel or eating.

To me that sounds like a very typical work week without spectacular overtime, crunch, hustle, whatever.

It says that some CEOs work more hours, but doesn't correlate that with higher productivity.

It says that few work less than 40 hours per week discounting meals and travel.

50 hours per week is 10 hours per day. Maybe like 8 to 6. Anyone complaining about expectations for crunch time would relish hours like that.
