Mercer's research emphasizes that employee engagement is critical for achieving positive business outcomes, as engaged employees drive productivity and organizational success. The study identifies four key drivers of engagement: the work itself, trust in leadership, recognition and rewards, and effective communication, noting that these drivers can vary by country and organization. Through its 'What's Working' surveys, Mercer provides insights into employee attitudes and helps organizations tailor their engagement strategies to better align with employee needs and cultural contexts.
