It depends on the person's symptoms as well as the severity. I work 31 hrs a week on my feet and can barely survive it without living in the hospital once every 6 weeks for a week at a time. I was working 5 shifts a week and that almost killed me. Other people are more functional, but many people cannot work at all. I can't even extrapolate a figure regarding percentage of sufferers who I think are working or able to work.
