Despite societal shifts in attitudes towards gender and sexuality, LGBTQ+ individuals continue to experience multiple forms of labour-market disadvantage – including greater unemployment, lower job satisfaction, and slower career progression. However, existing scholarship has paid little attention to the comparative employment conditions of LGBTQ+ and non-LGBTQ+ individuals. Leveraging unique data from a large, Australian, employer-employee dataset (2024 AWEI Employee Survey), we fill this knowledge gap by examining the relationships between LGBTQ+ status, non-standard employment (NSE), and workplace well-being. Consistent with our theoretical expectations, we provide novel empirical evidence of the ‘double whammy’ faced by LGBTQ+ employees in relation to NSE. On the one hand, LGBTQ+ employees are more likely to be in certain forms of NSE than non-LGBTQ+ employees; on the other, their workplace well-being is more negatively impacted by these employment arrangements. These findings bear important lessons for policy and practice, indicating that closing the gap between LGBTQ+ and non-LGBTQ+ workers requires careful consideration of their employment arrangements and the circumstances that surround them.
