ABSTRACT Communication problems that frequently occur in the workplace can be addressed through mindfulness, particularly mindfulness in communication, which refers to an individual’s ability to be fully present, open, and to respond calmly during the communication process. One aspect of workplace behavior related to mindfulness in communication is voice behavior, defined as employees’ tendency to express ideas or suggestions aimed at encouraging organizational improvement or change. This study aimed to examine whether there is a relationship between mindfulness in communication and voice behavior among employees in the Food & Beverage (F&B) industry in Jakarta. This study employed a non-experimental quantitative approach using purposive sampling as the data collection technique. The instruments used were the Mindfulness in Communication Scale and the Voice Behavior Scale. A total of 246 participants were involved, consisting of employees who were currently or had previously worked as operational employees in the F&B industry in Jakarta, worked in team-based F&B companies rather than individual enterprises, and had a minimum of six months of work experience. The results of the analysis indicated that mindfulness in communication had a positive correlation with voice behavior. These results suggest that higher levels of mindfulness in communication are associated with higher levels of voice behavior among operational employees in the F&B industry in Jakarta. Based on these findings, organizations may develop programs focused on enhancing mindfulness in communication and voice behavior to support better communication and increase employee contributions within the organization.
