Amazon has fired two employees after they publicly denounced the company’s treatment of warehouse workers during the coronavirus pandemic. The user experience designers Emily Cunningham and Maren Costa said on Tuesday they had been fired after internally circulating a petition about health risks for Amazon warehouse workers during the Covid-19 crisis. Costa and Cunningham had received repeated warnings for speaking out on the company’s climate record during their time organizing with Amazon Employees for Climate Justice, a group that made public calls for the company to do more to fight the climate crisis. An Amazon spokeswoman confirmed the two employees were fired for “repeatedly violating internal policies”, which prohibit employees from commenting publicly on its business without corporate justification and approval from executives.
