How to Onboard a New Manager Without Losing Your Team

Episode 20 of Manager Mondays tackles a tricky leadership transition: bringing in an external manager over a tenured team. Lucas and Luna break down the research from a 2023 MIT Sloan study on 'successor syndrome' and walk through a real case from a mid-size SaaS company where a senior IC was promoted to lead her peers—and nearly quit. They cover the three specific conversations every new manager needs in their first 30 days, why skipping the 'expectations audit' creates political fallout, and how to protect institutional knowledge when the new boss doesn't know the internal playbook. If you've ever seen a team splinter after a new manager arrives, or you're that manager yourself, this episode gives you a concrete framework: the stakeholder map, the trust ledger, and the 90-day listening tour. No fluff, no generic advice—just a repeatable system for making transitions stick without losing your best people. #ManagerMondays #PeopleManagement #TeamLeadership #FirstTimeManagers #NewManagerOnboarding #SuccessorSyndrome #LeadershipTransition #PromotingFromWithin #TrustLedger #StakeholderMapping #90DayListeningTour #ExpectationsAudit #MITStudy #InstitutionalKnowledge #Careers #FexingoBusiness #BusinessPodcast #ManagementTips Keep every episode free: buymeacoffee.com/fexingo
