A group of shareholders is demanding Amazon run an independent audit to assess how the company treats its employees. Mary Beth Gallagher, the director of engagement at Domini Impact Investments, the group that filed the resolution, told Cheddar it wants to invest in companies that protect shareholders and specifically noted concerns about productivity quotas and employee surveillance. The company's worker safety initiatives have been questioned even before a tornado killed six people at an Amazon warehouse in Illinois this month. "What we want to see is Amazon centering workers' voices and having an independent review that hears directly from workers themselves who know the conditions that they're working under and the pressures they face," she said.
