If a team can't meet a deadline, it's a management problem, and not the team's problem. This means that, somewhere along the way, the project didn't go as planned and a course wasn't corrected. So, Rule Number 1 to avoid burnout is "Manage the project and expectations well" (See: Help! We are behind schedule!).
Rule number 2: Never ask more of your team than you would ask of yourself (and you mustn't ask yourself to work nights and weekends). Other organizations might ask their teams to pull longer hours when the going gets rough. This is a laser-focused bullet train to attrition and long-term inefficiencies. Webflow cares deeply about its team, not only professionally, but personally, so we must do our best to manage our time well.
