"Make Amazon Pay", a campaign coordinated by the UNI Global Union, said strikes and protests would take place in more than 30 countries from Black Friday - the day after the U.S. Thanksgiving holiday, when many retailers slash prices to boost sales - through to Monday.
In Germany, Amazon's second-biggest market by sales last year, around 250 workers were on strike at a Leipzig warehouse and around 500 at an Amazon warehouse in Rheinberg, trade union Verdi said on Friday.
More than 200 workers were striking on Friday at Amazon's warehouse in Coventry, England as part of a long-running dispute over pay.
The striking workers were chanting their demand for a pay rise to 15 pounds ($18.69) an hour.
Amazon has remained popular in Europe even as rivals like Shein and Temu have seen rapid growth.
