Amazon reportedly fired several senior managers at jfk8, the facility in Staten Island, New York that recently voted to unionize. Some of their co-workers see it as a punishment for the union’s win.

It could mean that managers were tasked with keeping the Union from winning, and that they were fired for failing to do so. But it could also mean that the managers had helped the union in some way, and are being fired for that.

Amazon has contested the results of the election, saying the union and the National Labor Relations Board’suppressed and influenced’ voters. The company has been accused of union busting, preventing workers from exercising their rights, and firing workers in retaliation for organizing.

A report from last year noted that Amazon’s goal is to let go of its lowest-performing employees each year. Some of them had recently received positive feedback about their performance.
