The National Labor Relations Board (NLRB) has found that eBay has violated the rights of unionized workers at TCGPlayer, a trading card marketplace owned by the company. This comes in response to charges filed by the Communications Workers of America back in March of this year. eBay has allegedly refused to recognize TCGPlayer’s worker union and it delayed participating in any bargaining practices and it has also refused to divulge any information with the group that the union is legally entitled to.

As part of its examination of the issue, the NLRB said that because eBay and TCGPlayer broke the law, the company must face legal consequences for its union-busting practices. The union, which officially formed in March following numerous anti-union actions from eBay and TCGPlayer, was denied representation during disciplinary investigations. The NLRB also found that eBay was changing working conditions and benefits without engaging in bargaining with the group. On top of that, eBay is said to have even enforced rules that would punish any workers’ elections to unionize.

While the NLRB lays out evidence of eBay’s union-busting practices, it did not officially issue a decision on the matter. The agency is still waiting on the company’s response to the issue. “Now that the board has come to a decision on eBay’s illegal practices, we hope the company will see the light, obey labor law and engage in good faith bargaining practices so that workers can secure a strong union contract,” Dennis Trainor, Communications Workers of America District 1 Vice-President, said in a statement. eBay could not be reached for comment.
