The decision comes at a delicate moment for Amazon as it awaits the outcome of its Bessemer, Alabama, workers’ vote on whether to make their warehouse the company’s first unionized facility in the country.
Cunningham and Costa, who gained prominence for pushing the company to do more on climate change, about a year ago questioned Amazon’s pandemic safety protocols and worked to raise money for warehouse staff at risk of contracting COVID-19.
In a statement, Amazon said it supports workers’ rights to criticise work conditions, but that doing so does not absolve staff of breaking lawful rules. “We terminated these employees not for talking publicly about working conditions, safety, or sustainability, but rather, for repeatedly violating internal policies,” it said.
Amazon on Monday did not specify what those polices were.
Cunningham and Costa did not immediately comment. Marc Perrone, international president of the UFCW union whose local unit helped file the charge, said in a statement: “Today is a reminder that Amazon will break the law to silence its own workers who speak out.””
The New York Times earlier reported the news.
