They did have a shelter area. It wasn't enough, most can't survive a direct hit, it's just a fact of life in that area. And if you leave every time there a tornado in the area you don't work for many months of the year. Instead you go to the shelter when it's very close, which is what they did (10 to 15 minutes before). Don't listen to activists, they usually aren't interested in the employees, rather they just want to criticize the "external enemy". Offtopic but I've noticed most "environmentalists" are the same way, they aren't interested in improving the environment, rather they are just misanthropes.
