In fact, I'm undertaking research now with a team that is looking not at health issues generally but at specific disability issues. What you find is that there are a certain number of workers who are in some sense prefiltered out of jobs because of their health condition. Usually, it's what we would call a disability from the perspective of having a potential impact on their ability to the job, or perceived impact on their ability to do the job. Once they're on the job, the issue is the extent to which the employers accommodate the disability. If they don't accommodate the disability, that can have a direct impact on the person's performance and subsequent promotions, training opportunities, or even opportunities for other jobs.
Not being an expert on the general health side but having looked at the disability side, I believe it's an extremely important factor. We're in the midst of an aging population and workforce. Since the workforce is being skewed toward the older ages, all of these problems are becoming more accentuated. Now is definitely the time to start thinking about these issues.
