The results could alter the shape of the labor movement and one of America’s largest private employers.
Ms. Costa and Ms. Cunningham, who worked as designers at Amazon’s Seattle headquarters, began criticizing the company publicly in 2018. They were part of a small group of employees who wanted the company to do more to address its climate impact. The group, Amazon Employees for Climate Justice, got more than 8,700 colleagues to support its efforts.
Over time, Ms. Cunningham and Ms. Costa broadened their protests. After Amazon told them that they had violated its external communications policy by speaking publicly about the business, their group organized 400 employees to also speak out, purposely violating the policy to make a point.
They also began raising concerns about safety in Amazon’s warehouses at the start of the pandemic. Amazon fired Ms. Costa and Ms. Cunningham last April, not long after their group had announced an internal event for warehouse workers to speak to tech employees about their workplace conditions.
After the women were fired, several Democratic senators, including Elizabeth Warren of Massachusetts and Kamala Harris of California, wrote Amazon expressing their concerns over potential retaliation. And Tim Bray, an internet pioneer and a former vice president at Amazon’s cloud computing group, resigned in protest.
Mr. Bray said he was pleased to hear of the labor board’s findings and hoped Amazon settled the case. “The policy up to now has been ‘admit nothing, concede nothing,’” he said. “This is their chance to rethink that a little bit.”
