In Italy, Spain, Germany, and France, workers planned to strike for 24 hours or more. The Italian publication Corriere della Sera reported that managers were having to step in and package items to deal with demand.
UNI Global, the trade union helping coordinate the walkout, said roughly 2,400 workers were on strike in Europe, but people on the ground are reporting higher numbers of protesters.
Amazon Germany told Reuters that 620 employees participated in the strike across two of its warehouses, while the German union Verdi told Business Insider that 1,000 workers were walking out.
In Spain, unions said 1,600 employees had downed tools for the day.
