As I said during disco they would be able to inspect the warehouse and if they can find any trace of it (which they will) then that is all the evidence they need to go to a “decider of fact” (the jury). And despite your calculation of time, more time spent outside amazon warehouses does not mean employees are more likely to get the virus outside the warehouse, only that there was more time to get the virus somewhere else. there are “hotspots” after all. But let’s assume what you said was true, to even make that argument in court For a jury to consider you are at trial and need an expert witness to introduce the argument...that’s a lot of cost for a big risk, it settles.
