> When there's tornadoes about, the first thing companies should tell their workers is 'Find somewhere safe to shelter, don't worry about the job or reducing damage to the company.
I worked in the Midwest for a number of years. Every time there was a tornado siren, an attempt would be made to alert everyone in the building. We were to go to the shelter in the basement and/or 1st floor.
Only a minority would actually get up and move there. Worse, many would go to wall size windows to see the storm outside. There's no way security can force the majority of workers to move. All they can do is walk around and warn. Did people not go because they were worried about productivity dropping? No! They didn't go because they hear these sirens often enough (a few times every summer) and simply ignored them, because the odds of getting hurt appear low.[1]
So to me, reading people imply that they got killed because of capitalism is ludicrous. Simpler explanations exist.
Also, tornado shelters are not perfect.
Also, tornado shelters at work locations often are safer than ones at home. I know when I lived there, I always preferred to be in the office when a tornado siren hit. My home didn't have a basement, and you're not supposed to be in any room that has a window. That meant I should be either in the kitchen or the bathroom. At least the shelter at work was much bigger - you could walk around, etc.
[1] For that city, a tornado touches down there once every twenty years, and even that will be in a limited part of town. Not saying this is a good rationale, but humans will be humans.
