Amazon workers protest in Washington on Black Friday

Protesters gathered outside an Amazon Fresh store in Washington, DC on Black Friday to press for higher wagers and better working conditions at Amazon.

Protesters held signs that read, "Make Amazon Pay" and "Amazon Global Greed."

Activists in more than 30 countries have called for protests against the US-based company on the annual "Black Friday" discount campaign.

The campaign "Make Amazon Pay" accuses Amazon of exploiting both the environment and its own employees and demands better pay and the conclusion of binding collective agreements.

Overseas, work stoppages were planned at 10 of Amazon's 20 German warehouses and shipping centers, according to the union.

Amazon said did not expect any impact on customers.

Last week, a federal judge ordered Amazon to stop retaliating against employees engaged in workplace activism, issuing a mixed ruling that also hands a loss to the federal labor agency that sued the company earlier this year.

The ruling came after the National Labor Relations Board sued Amazon and sought the reinstatement of a fired employee who was involved in organizing a company warehouse on Staten Island, New York.

The judge ruled there was "reasonable cause" to believe Amazon committed an unfair labor practice by firing the worker. She issued a cease-and-desist order directing Amazon to not retaliate against employees involved in workplace activism. However, she denied the NLRB's request to reinstate the worker.
