An increasing body of work has found higher education to be a challenging and stressful environment. Meanwhile, research on workaholism, characterised by an uncontrollable urge to work excessively, has been gaining momentum. However, few studies have explored its impact within higher education. This study addressed this gap by conducting 27 semi-structured interviews with academics in the greater Dublin region, exploring the micro, meso, and macro-level factors influencing workaholism. Using a constructivist grounded theory approach, the study examined workaholism in higher education, unpacking Clark, Smith, and Haynes ([2020]. "The Multidimensional Workaholism Scale: Linking the Conceptualization and Measurement of Workaholism." "Journal of Applied Psychology" 105 (11): 1281-1307.) recent definition of workaholism as a multidimensional construct comprising motivation, cognition, emotion, and behaviour. Twelve participants displayed tendencies of excessive working and constant thoughts about work, driven by negative feelings when not working. These tendencies were rooted in motivations to gain control and build a personal brand. All elements of workaholism have micro, meso, and macro influences, understood through a transdisciplinary lens. As a result, this study calls for responsible, sustainable management within higher education to avoid the negative impacts of workaholism on academics, students, and institutions.
