Recently, the NLRB found reason to charge Amazon with allegations of illegal union busting such as refusing to bargain with the union representing workers at its NYC warehouse, restricting access to its facilities, and disciplining union leaders. While the NLRB has not yet taken any formal actions against the company, these findings are a precursor to issuing a complaint. If the case is not settled, and Amazon is charged with these allegations, it could potentially interfere with the company's 2021 nationwide settlement with the NLRB. Furthermore, in January, it was found that Amazon violated labor law in its resistance to the unionization efforts at the same Staten Island warehouse in this case.
