Although it's not a new concept, management books regarding employee engagement are a popular trend. They are an interesting point of view for both managers as well as employees.
The 2020 workplace: how innovative companies attract, develop, and keep tomorrow's employees today by Jeanne C. Meister and Karie Willyerd
The talent masters: why smart leaders put people before numbers by Bill Conaty and Ram Charan
The author, Liz, Wiseman contends that leaders fall into two distinct categories: Multipliers and Diminishers. Multipliers, those who liberate their employees to do their very best, invest in human capital and inspire excellence, are the exact opposite of Diminishers. Diminishers, in turn, are toxic, self-centered, and often know-it-alls, whose lack of managerial skills tend to tear down their employees. While many people land in the middle of this continuum, Wiseman creates an excellent framework for her theory. Anyone who reads this book will recognize the Multipliers and Diminishers in their lives.
