All companies strive for the same goal: to satisfy clients with the most relevant products and the best of service. And to succeed, they need their employees; engaged ones. Engaged employees make satisfied clients and ensure good business performance. This unbeatable equation should seduce any organization looking to create value. Engaged employees bring their passion, their sense of initiative and creativity to the office. So what levers, what tools, what miraculous alchemy can make an employee engaged? We look at four very different companies, each, with a unique vision of engagement: happiness at Zappos, conviviality at Pernod Record, entrepreneurship at La Poste and excellence at Netflix. All these companies have understood the essential: bringing all employees in on a common story based on shared values will make the difference.
