Thank you for raising this scenario.
It is not merely about credit.
It is about power asymmetry, responsibility and the integrity of the value system within the project.
In such a situation, a Project Manager should interpret the episode as a governance signal.
When a manager with strong stakeholder influence presents a team member’s idea as their own, the risk extends beyond individual unfairness.
The deeper risk is structural – innovation withdrawal, erosion of psychological safety and long term reputational damage if merit becomes subordinate to hierarchy.
A disciplined response would follow three steps.
First, verify the facts and understand the impact on the contractor.
Psychological safety is a performance asset.
Second, address the manager privately and respectfully, framing the issue around credibility, stakeholder trust and sustainable team performance. Influence shapes culture.
If influence absorbs recognition, the system gradually optimizes for politics instead of value creation.
Third, create a proportionate opportunity to restore authorship, for example in a subsequent steering update, positioning acknowledgment as strengthening collective leadership rather than exposing fault.
If the behavior reflects a pattern, it becomes a structural governance concern that may require sponsor alignment around a clear norm: contribution and recognition must travel together.
Otherwise, the project accumulates hidden trust risk.
Under conditions of power imbalance, ethical leadership is not reactive confrontation.
It is the conscious protection of the conditions that enable people to contribute with courage while safeguarding the credibility of the system.
