This really doesn't feel like the right question. The only safe(ish) place in a tornado is being in a building or bunker rated for a tornado. The technology exists. I think I would ask: - Are insurance companies incentivizing building certified shelters by lowering insurance for those that get said building certifications? This question also applies to residential homes. - Are state and federal governments incentivizing building certified shelters by giving tax breaks to businesses that get said building certifications and have them inspected annually? - Are any construction companies providing services to retrofit buildings in tornado prone locations? If there is money to be made I believe this would become a thing. Whether people are working, eating or sleeping I think is not as relevant as mitigating the root cause of a well known risk and incorporating that into business cost and offsetting the retrofit with tax exemptions and write-offs. If you want your folks to keep working during a tornado, then design the building to handle one. Switzerland somehow managed to address this issue for an even less likely risk, as nearly all homes have a fallout bunker.
