This work demonstrates how to master the role of a deputy confidently and use it as an opportunity. Present yourself assertively and lead powerfully within certain boundaries. Achieve clear role definitions and division of labor with the boss. Convince, motivate, and engage teams. Advance your own career. With concrete tips, checklists, exercises, and reflection tasks. Bonus: E-book included. Deputies must perform leadership tasks under challenging conditions. Without disciplinary authority and often with a vague job description, they are expected to represent the boss in their absence and otherwise support him loyally. Deputies are under special scrutiny from both employees and management, as these positions are often used as a testing ground for future leaders. This book provides the necessary knowledge and tools in a concise and compact manner.
