While academics and practitioners seek reliable information on how best to support employee mental health, there is no consensus in the literature in terms of the use and awareness of Stress Management Interventions (SMIs). Our research objectives address these issues by identifying key factors predicting employee awareness of five SMIs on offer in their organization; and identifying key factors predicting employee use/not use of each of these five SMIs for those employees who know the benefit is available. Our partner in this research was the Canadian Armed Forces (CAF), a male-dominated hierarchical organization which recognizes and rewards those who adhere to “ideal worker” norms. All SMIs included in our study were available to all workers surveyed (n = 1627). We make two key contributions to the literature. First by identifying the factors predicting awareness and use of different SMIs, we provide information which should help key stakeholders develop strategies to address the above issues. Second, our ability to study benefit awareness and use in an extreme case environment allows us to explore the impact of workplace context and organizational culture on these topics.
