Guard the maker's calendar

Why this rule exists

The people who build things need long, uninterrupted stretches, and a single mid-morning meeting can wreck a whole day by splitting it into fragments too small to do deep work in. Managers, whose own days are already chopped into meetings, often don't feel this cost and schedule right through it. What looks like one harmless thirty-minute sync on your calendar can be the difference between a maker having a productive afternoon and having none. Protecting the shape of their day, not just its total hours, is real leadership.
