A spokesman for the Verdi labour union said about 500 of the around 1,200 workers at Amazon's distribution centre in Leipzig were expected to strike.
Amazon employs a total of 9,000 warehouse staff at nine distribution centres in Germany - its second biggest market after the United States - plus 14,000 seasonal workers.
Three of Amazon's German logistic centres were hit by a stoppages in the run-up to Christmas, although the company said deliveries were not affected.
Verdi wants Amazon to raise pay for workers at its German distribution centres in accordance with collective bargaining agreements for the mail order and retail industry.
However, Amazon 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.
