  This vision paper focuses on the mental health crisis impacting healthcare
workers (HCWs), which exacerbated by the COVID-19 pandemic, leads to increased
stress and psychological issues like burnout. Peer Support Programs (PSP) are a
recognized intervention for mitigating these issues. These programs are
increasingly being delivered virtually through Peer Support Systems (PSS) for
increased convenience and accessibility. However, HCWs perception of these
systems results in fear of information sharing, perceived lack of safety, and
low participation rate, which challenges these systems ability to achieve their
goals. In line with the rich body of research on the requirements and
properties of trustworthy systems, we posit that increasing HCWs trust in PSS
could address these challenges. However, extant research focuses on objectively
defined trustworthiness rather than perceptual trust because trustworthy
requirements are viewed as more controllable and easier to operationalize. This
study proposes a novel approach to elicit perceptual trust requirements by
proposing a trust framework anchored in recognized trust theories from
different disciplines that unpacks trust into its recognized types and their
antecedents. This approach allows the identification of trust requirements
beyond those already proposed for trustworthy systems, providing a strong
foundation for improving the effectiveness of PSS for HCWs. Keywords: Trust
