When you are working for an introverted boss, you can’t afford to be a slacker. To them, deadlines are critical. If there is a project that needs to be finished, your boss will need it by the agreed time or a.s.a.p. Of course, this is nobody’s fault. Many introverts are wired this way and hate missing deadlines. This is just how they are. They like to have a plan and be methodical and assume that you will meet their expectations.
