German labor union Verdi has called on workers at online retailer Amazon in Germany to go on strike on Thursday as a long-running pay dispute continues. Amazon is refusing talks about a wage agreement, Verdi negotiator Joerg Lauenroth-Mago said in a statement, saying workers at distribution centers in Leipzig and Bad Hersfeld were to walk off the job starting with the morning shift. Verdi wants Amazon to raise pay for workers at its distribution centers in accordance with collective bargaining agreements across the mail order and retail industry in Germany. 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.
