Regarding that part of the second edit: a very wise colleague of mine with managerial duties once told me that he expects people to give 50 to 70% every day. First, it’s unsustainable to give 100% all the time, and burnout has far worse direct and indirect consequences than simply scaling the operation up to allow more slack time. Second, when shit actually hits the fan and you need all hands on deck, there’s no more that can be given if you were already giving it 100%
