📊 Why manager retention matters: Managers who feel invested in are significantly less likely to leave. DDI (2023) finds lack of development is a leading reason managers exit, and replacing a manager costs 1.5–2× their salary in recruitment, onboarding and lost productivity. Extending development to the 40 currently without provision directly reduces this risk.

📊 Reach & Engagement: An additional 18 managers outside your current programme are projected to engage via podcast-style and short-form video formats — the same formats people already choose outside of work. These formats complement, not replace, your existing workshops; your enrolled managers continue their programme as normal while format-led learning extends meaningful development to managers who would otherwise receive nothing. This extended reach directly underpins the manager retention saving shown above.
