75% of managers admit to actively retaining their best performers. That’s the central figure of the Keller & Dlugos study published in Academy of Management Journal in 2023. Three managers out of four.
If you wonder why your internal mobility proposals always go nowhere, or why you’ve been told “your time will come” for 3 years, it’s not in your head. It’s documented.
What is Talent Hoarding?
Talent Hoarding is the active retention, by a manager, of their best collaborators within their team or department, against the interest of organizational internal mobility. It’s a locally rational behavior (the manager protects their team’s performance) that produces a destructive systemic effect (the best talents stagnate, disengage, or leave).
The Keller & Dlugos (2023) study is the first to measure this behavior at scale. Sample: 1,200+ managers in 30+ Fortune 500 companies, across 4 sectors (tech, professional services, manufacturing, healthcare). The figures below come from this study and complementary work 2023-2024.
The 8 key statistics on Talent Hoarding
1. 75% of managers admit actively retaining their best (Keller & Dlugos, 2023)
The founding figure. Note: this is self-reported. The real percentage is likely higher, because some managers retain without formalizing it as such (“we just couldn’t find a replacement”, “the timing isn’t right”).
2. Talent Hoarding increased by 123% between 2019 and 2022
Haegele (2022), LMU Working Paper. Documented retention episodes more than doubled in 3 years. Hypotheses: post-COVID shortage + Great Resignation + pressure on short-term performance.
3. A manager’s team performance depends 60% on their top 3 performers
Hence the incentive. If 60% of a team’s performance comes from its top 3 members, the manager has a direct interest in blocking them internally. It’s a logic of local optimization that doesn’t account for the global interest of the organization.
4. Talent Hoarding doubles the risk of external departure at 18 months
Documented boomerang effect. When a retained talent realizes they won’t progress internally, they switch to quiet quitting then external resignation. The manager who wanted to “keep their best” loses their best, but loses them more violently.
5. 80% of blocked internal transitions end in external resignation at 24 months
2023-2024 HR studies (PwC, Mercer). When a collaborator has applied internally and wasn’t taken (or was discouraged from applying), 8 times out of 10 they leave the company in the following 2 years. The blocking manager delays, they don’t avoid.
6. Externals paid 18% more than internals for the same role
Bidwell (2011), Administrative Science Quarterly. The internal/external pay gap precisely documents the asymmetry: hiring an external costs 18% more in salary than an internal for the same role, but organizations do it anyway. Consequence for you: your best salary leverage is to leave externally, not to negotiate internally.
7. Talent Hoarding reduces job satisfaction by 32%
When a collaborator identifies that they’re being retained, their job satisfaction drops 32% on average within 6 months (2023 employee engagement studies). It’s also the direct trigger of quiet quitting.
8. Transparency on promotion criteria is the main antidote
Organizations that publicize promotion criteria (required skills, milestones, deadlines) divide documented Talent Hoarding episodes by 3. You can ask your manager this question: “What are the precise criteria and the deadline for my next step?”. The silence or vagueness of the answer is itself a signal.
How to recognize that you’re a victim of Talent Hoarding
4 observable signals:
- You receive public praise but no real promotion in 18+ months
- When you ask for precise criteria for your next step, you get vague answers
- Your internal mobility proposals (other team, other project, other role) go nowhere or are discouraged
- Your manager says “you’re indispensable here” more than 2 times per semester
If you check 3 of these 4 signals, Talent Hoarding is very likely. You’re not paranoid.
How to escape (without accusation, with method)
Three steps validated by Expansion Bootcamp alumni:
Step 1, formalize the criteria request. Not a complaint. A methodical request, in writing. “To prepare my next step, can you confirm the 3 precise criteria and the target deadline?” If the answer is clear, you know what to do. If it’s vague, you have your answer.
Step 2, broaden the internal network. Talent Hoarding works when you only have one visibility (your direct manager). You take 2 coffees a month with managers from other teams or other departments. Not to apply. To be visible. Your next opportunities will likely come from them, not from your current manager.
Step 3, prepare plan B (external) in parallel. Not in panic. With method. Update your portfolio, exploratory conversations with 5-10 external contacts, precise identification of the next role (not a category, a role). You don’t have to use this plan B. But having it changes the dynamics of internal conversation.

P.S. Talent Hoarding is rarely intentionally malicious. Most managers don’t realize they practice it. That doesn’t change the effect on you. The rule: you don’t have to educate your manager, you have to protect your trajectory.
