Since the early 2000s, workplaces have been a focus of various LGBTQ policy interventions – addressing prejudice in selection processes, workplace bullying/harassment, as well ‘soft’ approaches to inclusivity. This working paper explores the contribution agent-based modelling (ABM) can make to the study of LGBTQ workplace inequalities and, conversely, how intersectional and queer theoretical insights from LGBTQ studies can inform future developments in ABM. We introduce an example LGBTQ workplace model, developed as part of the CILIALGBTQI+ (Comparing Intersectional Lifecourse Inequalities amongst LGBTQI+ Citizens in Four European Countries) project, to illustrate how ABM can address methodological binarism and bridge macro and micro accounts within LGBTQ studies of the workplace. The model is intended as an important starting point in developing the role of ABM in LGBTQ research and for bridging qualitative- and quantitative-derived insights. Likewise, in the working paper, we reflect on some of the theoretical and methodological tensions encountered in developing the model, and how we approached negotiating these through the research process.
