Talent hoarding is when a manager keeps a strong employee in their own team by blocking or discouraging an internal move, promotion or transfer that would help the person and the company. It is one of the main reasons an organisation’s internal mobility rate stays low even when it posts plenty of internal openings.
The manager is usually being rational about their own targets. The cost lands elsewhere: blocked employees often leave the company instead, and they tell colleagues why.
Researchers from Cornell and Penn State, including JR Keller, studied internal applications at a large US health services company and published the work in the Academy of Management Journal. As reported by Fortune in January 2024, managers who promoted more of their team members in the prior year received about 9 percent more internal applicants for their own openings, and about 12 percent more applications from high performers. In other words, letting people go appears to make a manager more attractive to internal talent, not less. Treat this as one well-designed study in one country, not a universal law.
Remove the veto: let employees apply without prior approval and inform the current manager only once they are shortlisted. Agree a standard release period, say 30 to 60 days, and give managers credit in their appraisal for people they develop and move on. An internal talent marketplace helps by making openings and gigs visible to everyone at once.
A short delay to finish a critical deliverable or train a replacement is reasonable. Holding someone indefinitely, or punishing them for applying, is not, and it tends to show up later as regretted attrition.
Compare internal application, rejection and exit rates by manager. A team with strong performers, almost no outward moves and above-average resignations among high performers deserves a closer look, and a stay interview with those people often confirms it.
