Ethical Consumer would expect a company to have a good supply chain policy, details of how it audited its supply chain, details of how it engaged with wider stakeholders such as trade unions, and how it managed difficult issues.

Ebay had none of this, as no details could be found. The company thus received Ethical Consumer's worst rating in the category.

An article in the Guadian in May 2016 told how by an overwhelming majority, eBay shareholders had voted against releasing information about any gap in pay between male and female employees.

The shareholder proposal, filed by Arjuna Capital, called for eBay to prepare a report about the company’s policies and goals to reduce any gender pay gap.

The company board recommended that shareholders vote against the proposal, stating that it would “not enhance the company’s existing commitment to an inclusive culture or meaningfully further its goal and efforts in support of workplace diversity”.

“Approximately 7.4% of shares voted were in favor of the gender pay proposal,” Johnna Hoff, communications director of eBay, told the Guardian.

According to the Form 8-K filed with the SEC following the meeting, there were 67,915,263 votes for the proposal and 735,069,693 votes against it.
