With a basis in the transactional theory of stress and coping, this study investigates the relationship between employees' exposure to workplace ostracism and their job performance, while also considering the mediating role of acquiescence silence and the moderating role of mindfulness. Multisource, three-wave data from employees and their peers in Pakistani organizations reveal that ostracism in the workplace hinders job performance because employees passively withhold relevant ideas about their work due to feelings of acquiescence. The mediating role of acquiescence silence is mitigated if employees can draw from their mindfulness trait. This study accordingly identifies a key mechanism - the passive withholding of pertinent ideas, based on submission - by which workplace ostracism hampers job performance, and it reveals how this process might be contained by encouraging employees' receptive attention and awareness focused on present experiences.
