BERLIN » Hundreds of Amazon.com Inc. workers are staging a strike in Germany and the union says there will be more to come in the run-up to Christmas unless the online retailer raises wages.

The one-day warning strike today at Amazon’s distribution centers in Bad Hersfeld and Leipzig were the latest of several as the ver.di union pushes for wage agreements similar to those governing retail and mail-order workers.

Amazon has already agreed to pay Christmas bonuses but ver.di says the concession isn’t enough and it "is in Amazon’s hands" whether there are more strikes.

Amazon says that its warehouses are logistics centers and employees are already paid on the upper end of what other workers in that industry earn.

Ver.di represents about 2,000 workers in Leipzig and 3,300 in Bad Hersfeld.
