Employment Litigation
Discrimination Claims
Under Staub, an employer is liable where a supervisor's discriminatory animus was a proximate cause of the adverse action, even though the ultimate decisionmaker harbored no bias.
An independent investigation may break the causal chain.

Why it Matters?
Independent investigation is the defense, but it must be genuinely independent rather than a review that accepts the biased supervisor's account without verification. Interviewing the employee, examining underlying records, and reaching a conclusion on facts the decisionmaker verified is what breaks the chain. Rubber-stamping a recommendation, however senior the approver, leaves the animus operative and the employer liable.
