Here's my view as an executive, if my folks regularly add hours to their day/week to get their job done they're not good at their job. If they're good at their job they know how to prioritize and they also know how to optimize and automate constantly so they can do more with less. They also do their form of zero base reporting or zero base budgeting constantly to get rid of what was once important that no longer is.

To be fair in senior leadership a 40 hour week probably isn't going to happen but you should swing between 55 hours and 30 hours depending on the week and average it to the mid to high 40s.

I suspect this isn't going to be a popular post, and I accept your down votes but would also like to hear your contrary view along with it if you don't mind.
