Laborers of online retailer giant Amazon.com protested on Monday in front of Amazon's German warehouses.
Labor Union "Verdi" rallied in front of Amazon's Warehouse in Germany on Monday, demanding improvements on their salaries and other working conditions.
Verdi reportedly called out workers to protest at Amazon distribution centers in Bad Hersfeld, Leipzig, Graben and Rheinberg.
A total of 9,000 warehouse staff and an additional 14,000 contractual employees works for the online retailing giant's nine distribution centers in Germany.
Germany is reported to be Amazon's second-biggest market following the U.S.
The strike started in Sunday night at 10 p.m. with the night shift workers at two distribution centers in Bad Hersfeld. Three other German Amazon distribution centers followed. The strike is expected to finish at 10 p.m. Tuesday.
A total of 5 out of 9 Amazon logistics centers protested, according to Verdi.
German labor union Verdi demands Amazon to increase its pay for workers at its distribution centers in Germany. They also negotiated with Amazon's mail-order and retail industry regarding their demands.
The labor union wants Amazon to pay its workers in Germany in accordance to a collective wage agreement in line with compensation in the German retail and logistics industry, rather than using its own payment policies.
Amazon allegedly underpaid workers, based on the current German retail wage agreement.
Amazon refused to give in to the worker's demands, saying that it treats warehouse staff as logistics workers and reiterates that they receive above-average salaries by the standards set by that industry.
However, increase in salaries between 2.1% and 3% were reported in an Amazon distribution center in Graben, Bavaria.
The group has organized several work standstills over the past year.Verdi had previously orchestrated walkouts at three of those distribution centers back in June and during the Christmas period last year.
