Amazon.com Inc. warehouse workers in Minnesota are planning to strike during Prime Day on July 15, one of the company’s biggest sales events. Bloomberg reports that about 100 employees are expected to walk out for a total of six hours to demand changes in labor practices, including converting more temporary workers to employees and relaxing productivity quotas that they say create unsafe working conditions.

Striking workers at Amazon’s warehouse in Shakopee, Minnesota, are led by the Awood Center, a workers’ rights advocacy group, and backed by the Service Employees International Union, the Teamsters and the Minnesota chapter of the Council on American-Islamic Relations.

According to an Amazon spokesperson, the company “offers already what this outside organization is asking for. We provide great employment opportunities with excellent pay – ranging from $16.25-$20.80 an hour, and comprehensive benefits including health care, up to 20 weeks parental leave, paid education, promotional opportunities, and more. We encourage anyone to compare our pay, benefits, and workplace to other retailers and major employers in the Shakopee community and across the country – and we invite anyone to see for themselves by taking a tour of the facility."
