When Mayer suspects an employee might burn out, she asks them to find their rhythm. They've come back with, "I need to be home for Tuesday night dinners," or "I need to be on time for my daughter's soccer games."
really bothers me. If employee burnout is a regular thing inside your organization, that's a serious issue that needs solving. But to have to ask permission to spend time with your family is ridiculous.
If you're working 130 hours a week, something is seriously, seriously wrong.
