The US online retail giant was hit by a series of strikes across Germany in the December holiday season, traditionally its busiest time of the year.

Ver.di has been in talks with Amazon for months over a collective bargaining agreement and a reclassification of employees in the distribution centres as retail workers, which would raise their pay. Amazon has insisted that the employees should be classified as logistics workers, arguing that they are not performing skilled jobs.
The strikes comes amid heightened scrutiny of working conditions for logistics employees at distribution centres. Zalando, Europe's largest online fashion retailer, was forced to defend its working practices this week after an undercover reporter claimed she had to walk up to 27km a day and that breaks were frowned upon. Zalando has embarked on legal action against the reporter, from television network RTL, after she used a hidden camera while employed by the Berlin-based start-up.
