A Day in the life of a CAD dork

As a CAD manager for a bespoke furniture manufacturer, I have to balance many tasks. I am required to bill at least 50% of my time to projects. Of the remainder, about 25% is non billable time (Holidays, lunch breaks e.t.c). On paper this gives 35% of my time left for CAD management tasks. In practice the needs of the projects always come first. I'm currently the CAD resource for two project teams. The drawing work comes in clumps, it is always feast or famine.
