>there are reports of cases with an incubation period of up to 27 days.

There is only one report based on one case of a 70 year old man in Hubei province, based on contact testing, and did not rule out that he contacted it later.

And this would be a total reasonable defense if they quarantine any worker who has any contact with anyone who is infected for any amount of time for 27 days.

But that' isn't a policy the company follows. Also they let him work during the 2 weeks he was most likely to be contagious.

What do you think is more likely, that after more than 2 weeks of not giving a shit about quarantining an employee, suddenly Amazon was worried about a 0.01% outlier of 27 days before symptoms showed, or that this was a retaliatory action for the worker attempting to organize a strike.

I sure know what I'd be placing a large amount of money on if I was a betting man.

Tangent: would you make a bet on a question of fact where there is no authority you and your betting partner mutually trust to decide?
