Amazon employs a total of 9,000 warehouse staff at nine distribution centres in Germany, its second-biggest market behind the United States, plus 14,000 seasonal workers.
Verdi wants Amazon to raise pay for workers at its distribution centres in accordance with collective bargaining agreements across the mail order and retail industry in Germany and has organised several stoppages over the past year.
Amazon, however, has rejected the demand, arguing that it regards warehouse staff as logistics workers and says they receive above-average pay by the standards of that industry.
