Abstract
This study examines how organizational policy changes, specifically, the decision to either abandon or expand prior sustainability and diversity, equity, and inclusion (DEI) commitments, affect employees' ethical behavior, with reporting honesty as the primary outcome. Drawing on psychological contract theory, we hypothesize that employees interpret sustainability and DEI commitments as implicit organizational promises, and that abandoning such commitments triggers perceived breach, eroding trust, and increasing opportunistic behavior (e.g., misreporting of time, budget padding). Doubling down on commitments is expected to reinforce trust and ethical reciprocity. We further propose that the justification framing accompanying the policy change (business-case vs. moral) moderates these effects.
