Thank you for raising this very important point. We have been trying to engage deeper with our business community locally and created a draft 1 pager about "Why Trauma-Informed Care is Good for Business". I had an MSW intern do a brief literature review to help us create the document. Unfortunately, we were unable to find many/any rigorous studies with pre/post evaluation data on the "impact" for employees. There is much more on the "impact" on clients/patients, but less about the workforce implications. What we did find mentioned was not quantified statistically, i.e. % reduction in injuries, illness, turnover, or % improvement in workplace satisfaction, productivity, etc.
Anyhow, I would be very interested in continuing this conversation with others and exploring putting something together. I'm certain there are others out there who understand this better. We have a partnership with some local researchers that might be able to help design a "post-only" evaluation tool if there are some organizations who have completed the "trauma-informed care transformation" and willing to conduct an evaluation with their staff?
Also, I've always loved this story about the trauma-informed shipyard as a good example of the business case for this work. Vigor Shipyard - https://www.theguardian.com/us...tion-men-masculinity
