Workers at US online retailer Amazon's distribution centre in the western German city of Koblenz have gone on strike over pay and conditions, a union spokesman said Saturday.
"The strike started early in the morning and will last all of Saturday," a spokesman for the union Verdi said.
The workers staged a walkout earlier in the week. The union is seeking greater security for workers and higher wages according to the rules governing the German retail and distribution industries.
Amazon counters that it is a logistics company and that it pays its workers at the upper end of the usual wage scale for that industry.
Meanwhile, the online retailer is reportedly planning a two-hour delivery service in Berlin.
Local couriers will be commissioned to deliver the orders and a store on the capital's Kurfuerstendamm shopping mile is being refitted to provide a warehouse for the service, newspaper Die Welt reported on Saturday.
The service is to begin in May and operate six days a week.
Amazon neither confirmed nor denied the reports. "There are currently no announcements on the matter from our side," a company spokesman said.
