What motivates employees? As a supervisor, you need to know why people arrive to work each day, why is them stay – and what drives them to perform at their finest. Regarding to Teresa Amabile and Steven Kramer, the very best leaders are able to create a cadre of workers who have satisfying internal work lives: consistently positive emotions; strong motivation; and beneficial perceptions of the business, their work, and their colleagues. To do this, you must create forward momentum in meaningful work – about The Improvement Principle and prevent the road blocks that undermine internal work lifestyle. Through rigorous analysis of nearly 12,000 diary entries supplied by hundreds of employees in a number of different organizations, Amabile and Kramer describe ways to foster progress and improve your people’s inner work life each day – along the way boosting long-term innovative productivity. The publication shows ways to remove common obstacles to progress, such as for example meaningless duties and toxic human relationships, and emphasizes how these factors can disrupt workers’ internal work lives. The Improvement Principle also points out how you can activate two causes that enable progress: “catalysts” – events that directly facilitate project work, such as apparent goals and autonomy; and “nourishers” – social events that uplift employees, including encouragement and demonstrations of respect and collegiality. Filled up with honest, real-life good examples, convincing insights, and practical advice, The Improvement Theory equips aspiring and seasoned leaders alike with the guidance they need to maximize people’s functionality.
