“My boss takes credit for my work”

What could be going on

Takes credit, deflects blame: Taking the wins and handing back the losses fits; check whether failures get pinned on the team.

Self-serving bias: They may genuinely remember the success as theirs; check whether they credit others anywhere.

Status motive: Fits if they are under pressure to look valuable upward, such as a review or reorganisation.

Grandiose narcissism: Fits if credit-taking sits with entitlement, need for admiration and little interest in others.

Organisational justice: Your anger may be about unfair process; check how credit and promotion are actually decided.

Machiavellianism: Fits if it looks calculated: done quietly, timed for visibility, and denied when raised.
