The fast-paced business environment and new work arrangements have elevated mental health risks, especially occupational stress and burnouts. Mental health becomes a critical aspect for occupational safety and health in office settings. Therefore, employers aim to improve employees’ well-being and safety at the workplace through dedicated health initiatives. Internet-of-things (IoT) technology is increasingly being used for such purposes. However, its implementation in the workplace is accompanied by privacy concerns. In this study, we aim to provide a meta-synthesis of existing IoT solutions for supporting employees’ mental health in office settings. We classify existing studies into use cases with possible implementation options. We discuss main challenges emerging from privacy concerns along the IoT data lifecycle. We contribute to the design of the future workplace through emphasizing the opportunity for the connected workplace in improving occupational health.
