The purpose of this qualitative multiple-case study was to understand the perceptions of fire service employees about generational conflict within fire service organizations across the United States. The findings of the study could allow fire service organization leaders to develop better conflict resolution practices related to generational conflict. A purposive sample of 23 fire service members, spanning four generations, were interviewed to explore general characteristics, attitudes, values, and behaviors within fire service organizations. Transcribed interview data were divided into categories to find shared phenomena and identify themes based on the participants' perceptions. The findings were categorized and coded, patterns were established, and themes were generated to answer the central research questions. Trustworthiness of the interpretations was achieved through member checking. The findings from this study revealed that the employees perceived conflict that has occurred between fire service members was not clearly identifiable as generational conflict. The fire service members perceived that the majority of conflict stemmed from biases, prejudices, preconceptions, a lack of communication, differences in work ethics, and the need for leadership development within the fire service. The implications of this study include the potential to increase interactions between younger and older workers and minimize conflict resulting from miscommunication among the different age groups.
