I should rephrase my original sentence. When I said what I said I didn't mean that fringedgentian could guarantee he/she would never be unemployed - but that these steps would minimize his/her risk from finding themselves back in unemployment.

To continue your analogy, you cannot guarantee that someone will never have an accident, but you can recommend precautions to minimize their risk. It is these precautions that I was trying to hint at in my prior post.
