Promoting by Tenure Instead of Competence Teaches the Team That Sticking Around Matters More Than Effort

Using time at the company as the main criterion for deciding who gets promoted — "she's been here longer, it's her turn" — seems like a fair, objective way to distribute growth opportunity within a team. That logic, though, ignores that the new position requires specific competence, which doesn't necessarily develop just from accumulating time at the company, and it sends a dangerous implicit message to the rest of the team about what actually gets valued.

Promoting by tenure instead of competence teaches the team that sticking around matters more than effort. Whoever developed real skill but arrived later learns that patiently waiting is worth more than actively developing — an incentive that, over the long run, hurts exactly the people who contribute the most.

Why tenure is an easy but misleading criterion

Time at the company is easy to measure objectively — just count how many years the person has been there — and hard to dispute, because it requires no subjective performance judgment that could generate disagreement. That administrative ease is exactly what makes this criterion so appealing to whoever has to make the promotion call, even though it's, in most cases, a weak predictor of real success in the new role, which requires specific competence that tenure alone doesn't guarantee.

Calibrating promotion by the actual competence required

The practical alternative is to explicitly map which specific skills the new position actually requires — the ability to make decisions under pressure, the ability to develop other people, technical mastery of a specific process — and evaluate each promotion candidate against that specific map, instead of simply against how long each one has been at the company. That evaluation requires more work and more subjective judgment than just looking at a hire date, but it reflects far more accurately who is actually prepared to take on the new responsibility.

What happens to whoever has competence but not tenure

When seniority is the dominant criterion, the person with real competence but less time at the company often watches less capable colleagues get promoted just because they arrived first. That observation sends a clear, demotivating message: developing real skill and delivering consistent results matters less, in practice, than simply waiting your turn. For that high-potential person, that lesson tends to be exactly the kind of signal that motivates them to look for growth opportunity somewhere else, where competence is actually what determines advancement.

Recognizing tenure without using it as a promotion criterion

Recognizing and valuing time at the company doesn't need to disappear entirely — it can keep existing through other mechanisms, like specific public recognition or a benefit tied to tenure, that aren't directly linked to the decision of who takes on a position of greater responsibility. Separating these two types of recognition — one for loyalty and longevity, another for the specific competence a new role requires — lets you value both without compromising the quality of the decision about who should actually take on each position.

An example of the cost of promoting by seniority

A company promotes, into a team leadership position, the person with the most tenure on the team, despite another person, with less time there, having repeatedly shown more ability to organize process and develop colleagues. The person promoted by seniority struggles with the new role, because the specific competence leadership requires was never genuinely developed — while the more capable person, watching that pattern repeat, starts actively considering opportunities outside the company.

The bottom line

Before using time at the company as the main promotion criterion, it's worth asking whether that specific person actually developed the competence the new position requires, or whether they're being promoted simply because their chronological turn came up. Tenure can be recognized in other ways — but when it becomes the criterion that decides who takes on more responsibility, it teaches the whole team that waiting is worth more than developing, a lesson that costs the most with exactly the people worth keeping the most.
