Owing to the growing public concerns about environmental sustainability, the importance of sustainable workplaces has increased. Despite knowing that employees can play a vital role in achieving workplace sustainability, less attention has been paid to understand how employee attitude toward the use of environmentally sustainable work practices (ESWPs) can be developed. We examined the effect of intervention on employees' knowledge about ESWPs. Subsequently, a latent change model was tested to examine the effect of change in knowledge on change in intentions through change in employee attitude toward ESWPs. A pretest-posttest design was used in a field quasi-experiment (N = 51) where 28 and 23 employees from restaurant industry were assigned to experiment and control groups, respectively. Employee knowledge about ESWPs and other variables were measured by using questionnaires from existing literature. The results indicate that intervention improved employees' knowledge by 87% (mean difference = 1.91; p < 0.01) compared with those who did not receive intervention (mean difference = 0.17; p > 0.05). The change in knowledge caused a significant change in attitude and, subsequently, the intentions to use ESWPs. Workplace sustainability can be achieved by using knowledge-based persuasive interventions to improve employees' knowledge, attitude, and intentions toward using ESWPs.
