A group of New York legislators, top unions and Amazon employees wrote a letter to CEO Jeff Bezos Wednesday calling on him to enact greater protections for warehouse employees who continue to work during the coronavirus outbreak.

In a letter to Bezos, the 45 New York lawmakers, advocacy group Amazon Employees for Climate Justice and several unions, including AFL-CIO and the Service Employees International Union, called on Bezos to better protect warehouse workers.

"You claim to have adopted a number of practices to sanitize worksites and protect workers," the letter says. "But a compelling number of workers have come forward -- and even run the incredible personal risk of walking off the job -- to report that the actual situation in warehouses does not match Amazon's public relations statements. Your workers deserve to have full protections and to be confident that they are not carrying COVID-19 home to their families."

An Amazon spokesperson told CNBC in a statement that the group's accusations are "unfounded." The spokesperson added that the company has implemented a "broad suite" of new benefits changes for employees since the pandemic unfolded and put in place a number of new safety measures at its facilities to protect employees.

"Nothing is more important than the safety of our teams," the spokesperson said. "Since the early days of this situation, we have worked closely with health authorities to proactively respond, ensuring we continue to serve customers while taking care of our associates and teams."
