Covid-19 can strike Wall Street executives and janitors alike. But try telling that to Amazon’s workforce. Several of its employees have been fired for voicing fears about exposure to the virus. Amazon’s workers are being treated like “fungible units of pick-and-pack potential,”  said Tim Bray, a senior Amazon engineer who this week resigned in protest. Meanwhile, Jeff Bezos, the company’s chief executive, earned an estimated $149,353 a minute before the pandemic struck, three times the annual US median income. Amazon’s revenues have soared since then.
