Tip of the Week: Have you got your boss's number? Author Michael Goldberg uses the philosophical system known as the enneagram which divides people into nine personality types. If, for example your boss is a seven - innovative but impulsive - Goldberg suggests you `enforce boundaries and deadlines, embrace their enthusiasms and resist playing the heavy - sevens avoid conflict at all costs'. His book, Getting Your Boss's Number is published by HarperCollins.
