Book excerpt: Managerial styles are influenced by habit, familiarity, and workplace culture. It's no wonder that well-intentioned professionals doing their best to be good organizational leaders often repeat unhelpful supervisory practices experienced in their early careers, even if they disliked them at the time. In the DUH! Book of Management and Supervision, the author disagrees with many accepted leadership principles (unabashedly referring to them as myths) and makes new and different approaches easier to imagine. Her challenging and controversial concepts illustrated with poignant stories suggest common-sense and immediately applicable alternatives more suitable in today's workplace.
