Outline of Final Research Achievements

A 2011-2013 Grant-in-Aid for Scientific Research (Project Number 235304) revealed that able-bodied people who had close contact with people with disabilities had higher levels of job satisfaction and improved company performance. However, research into the mechanism remained an issue. This research revealed the following points: (1) Psychological safety increases in workplaces where people with disabilities are present, (2) Work performance of able-bodied employees improves, and (3) Synergy effects occur when working outside a facility because there is less contact with able-bodied employees at the workplace. (4) people with disabilities and able-bodied people can come into contact through closely related work; (5) it has the same effect as trial training for people with mental disabilities; and (6) it can be expected to increase wages.

Academic Significance and Societal Importance of the Research Achievements

障がい者を受け入れた職場は、工程や指示書の見直しが図られ健常者も働きやすくなるという分かりやすいメカニズムだけでなく、心理的安全性が高まることによってイノベーションやリスクマネジメントを進めやすい職場になるという、業績に影響を及ぼすメカニズムが解明できた。それによって障がい者と健常者の接触による業績改善が疑似的な連関現象でないことが明らかとなった。この現象を生むためには、障がい者がやりがいをもって就労を継続できる職場になっている必要があり、合理的配慮を伴う社会的包摂が企業の業績を改善することを示し、社会と企業の利害の交点を導くことができた。
