Gallup’s latest report estimates that low employee engagement costs the global economy US$8.9 trillion, or 9% of global GDP and examines what leaders can do to improve the health and productivity of the world’s workforce. The report explores the relationship between employee engagement and a range of key business outcomes, finding that high-engagement business units are likely to see significantly higher employee wellbeing – as well as higher productivity, profitability and sales – than low-engagement teams.
