Background: A multi-phase Canadian study was conducted as part of a large-scale community and academic research partnership focused on understanding and improving the employment experiences of people with intellectual disabilities. Method: This multi-method study utilized a sequential approach, using findings from qualitative interviews (n = 28) to inform an online survey (n = 149). Participants were invited to share their experiences with paid employment or with persons with intellectual disabilities. Results: Thematic analysis of data across interview and survey findings resulted in six themes: (1) assumptions and attitudes, (2) knowledge and awareness, (3) accessibility of processes, (4) use of accommodations, (5) workplace relationships, and (6) supports and resources. Conclusions: A holistic and systemic approach has the potential to improve inclusive employment experiences of people with intellectual disabilities. Action is needed mainly at the policy and employer level to reduce barriers and improve on facilitating measures reinforced by the themes shared in this study.
