Earlier quoted context omitted.
The article doesn’t support what you are saying. Do you have evidence to support these theories? What happened is terrible and is part of a much broader natural disaster. Trying to turn this into some shallow Amazon shaming is unfortunate.
The facts we have are: Amazon kept a warehouse open and operational, including bringing a new shift in, during a Tornado watch for the area. (this is in the article) edit r.e. this point: other commenters have noted that while the circumstances for a tornado arising are known in advance, the tornado appears quickly enough that realistically the only option if workers are in the building at that point is to move them…
The bigger issue imho is that these employees don't seem to have been in a tornado shelter during a tornado warning?
