In the wage dispute with Amazon that has been smoldering for years, the Verdi union is calling on employees at seven locations in Germany to go on strike.

The work stoppages in Leipzig, Rheinberg, Werne, Bad Hersfeld (two locations) and Koblenz, some of which lasted several days, are to begin on May 2nd, the union announced on Sunday.

The wage dispute at Amazon has been going on since 2013.

Verdi demands collective agreements for the employees in the German Amazon shipping centers, as they are common in retail and mail order.

Amazon, however, takes agreements in the logistics industry as a benchmark, in which less is paid.

According to Amazon, it does not expect any effects on customers.

They believe in a combination of fair wages and attractive additional benefits.

All employees in logistics at Amazon earned upwards of twelve euros gross per hour plus extras.

After 12 and 24 months, the salary increases automatically.

According to Verdi, the strike is also intended to set an example against the "constant monitoring and behavioral controls by Amazon".

"We know the company was spying on its employees.

Workers have a right to know if Amazon is collecting video, audio, social media, union membership or other personal data in violation of EU data protection laws,” said Christy Hoffman, general secretary of UNI Global Union , which represents 20 million workers in 150 countries worldwide.

In the US, in April in the Staten Island borough of New York, workers pushed through the first union at Amazon in the United States.
