That kind of sounds like sensible corporate behavior to me. What is it exactly that you have against this decision?
Until there is more information, I can totally picture a scenario where Amazon uses the excuse that they can remove a troublesome employee from leading a walk-out by (falsely) suggesting they have been in contact and need to self-isolate (the pay is nothing for them). When the employee disputes that and come in they get to fire the individual under the pretext that he was not behaving appropriately and endangering other workers.
*until mass consumerism and racing to the bottom led to these massive organisations flouting human rights but just out of view of the average consumer
It was not "corporate policy" - it was culture.
Coming to work sick and potentially infecting others is the opposite of failure isolation.
The key here is that you don't know if the accusation was true or false, but you arguing as if you do.
Which, in the language of Information Theory, is called a bias.
That because we don't know, you have to view the statement from the Amazon spokesperson as another unverified fact. Which, if you read your original response, you didn't. In this case, the information bias came from you. I was (possibly not clearly) trying to point out that lack of verification of the claim he was sick and/or in contact with somebody who was is important, specifically because it is advantageous for Amazon that everyone believe it to be true. I am not saying it isn't. We just don't know. Hope that makes it clearer.
