This article addresses the decline in manager engagement as revealed by Gallup's 2026 State of the Global Workplace report, which records global employee engagement at 20 per cent — its lowest since 2020 — and a nine-point drop in manager engagement since 2022. The author, drawing on 20 years of HR experience, argues that the crisis is structural rather than personal: the manager role has accumulated administrative, operational, and relational responsibilities that were never coherently designed into it, producing what the author terms a 'five-legged sheep' (mouton à cinq pattes). Key evidence includes Deloitte's 2025 finding that only six per cent of Gen Z identify leadership as a primary career goal, Robert Walters' report that 52 per cent of young professionals do not want to manage, and the observation that wellbeing programme participation rarely exceeds 25 per cent. The author contends that AI presents a structural opportunity to strip administrative tasks from the manager role and redesign it around uniquely human capabilities — coaching, judgment, and team development. The conclusion drawn is that organisations responding with role redesign rather than wellbeing interventions will produce more effective, sustainable management layers. Key insights: Global employee engagement has reached 20 per cent — its lowest since 2020 — with manager engagement specifically declining nine points since 2022, signalling a concentrated structural failure at the management layer. The manager role was never coherently designed; it accumulated administrative, operational, and people responsibilities by default, creating an overloaded and poorly scoped position that the author characterises as a 'five-legged sheep'. Gen Z's rejection of management roles — with only 6 per cent citing leadership as a primary goal and 52 per cent explicitly declining to manage — is framed not as a values shift but as a rational cost-benefit response to an outdated and overburdened job description. Practical takeaways: Auditing what managers actually do via calendar analysis rather than job descriptions can reveal the gap between formal role design and operational reality — a precondition for meaningful role redesign. Reducing manager-to-team ratios toward research-supported spans of 1:8 to 1:12 is identified as a structural correction, with current ratios of approximately 1:4 attributed to compensation architecture failures rather than genuine organisational need.
