There are many conditions that make it near impossible to work full time with enough consistency to support yourself. So many cancer treatments cause permanent damage, so even if you are in remission, you’re too ill to work. Complex medical problems that require frequent, unpredictable visits to clinics are simply incompatible with hourly work and have a significant impact on 9-5 salaried positions because so many clinics only operate during those hours. Add to that, people who work in manual labor positions are often at risk for injury, both acute and chronic, which means they can’t do the jobs they are qualified to do. There has to be a support system for cases like this where you need to transition to a new work regimen depending on your new limitations. If that support system isn’t there, isn’t reliable, or adds additional burden, it’s not going to help people recover. Making people feel worthless because they are temporarily or permanently unable to work is not a solution for anyone who isn’t an asshole.
