The study examines the conditional indirect effect of perceived leader greenwashing on
employees' eco-voice behavior and explores the mechanisms through which this effect unfolds.
Eco-voice, a discretionary form of pro-environmental action, is critical for translating
organizational sustainability goals into frontline practices, yet remains highly sensitive to
leadership authenticity and trustworthiness. Data were collected in three phases from 318 fulltime
employees across 98 green certified hotels and analyzed using partial least squares
structural equation modeling (PLS-SEM). Findings reveal that leader greenwashing negatively
influences eco-voice both directly and indirectly by eroding trust in leaders' ability and
integrity. The employees' eco-voice was more strongly shaped by competence-based trust and integrity-based
trust. Additionally, descriptive social norms moderated these relationships, strengthening
the translation of trust into eco-voice. These findings highlight the interplay between leadership
authenticity, trustworthiness, and workplace norms in shaping employees' willingness to raise
environmental concerns, and they underscore the fragile yet vital role of eco-voice in advancing
organizational sustainability.
