Four moves for keeping and growing the person you can least afford to lose, not a general essay on employee engagement.
01
Ask what they actually want before you guess
Managers tend to assume high performers want a promotion. Some do. Others want a harder problem, more visibility, or less of you in their work. Ask directly instead of building a plan around a guess.
02
Give them something hard, not something extra
Loading a strong performer up with more of the same work reads as a punishment for competence. A genuinely harder problem: one with real ambiguity or ownership, is what actually keeps someone engaged.
03
Don't let "high performer" quietly become "highest workload"
It's the easiest trap in management: give the important thing to the person who'll definitely handle it. Do that enough times and your best person is also your most burned out person, and you did it to them.
04
Say the retention part out loud
If you value someone and you're worried about losing them, tell them that directly: not as flattery, as fact. People who feel genuinely seen are less likely to start quietly looking, and the ones who are already looking will at least tell you first.
