Just to put the "VerDi" press release that is, sadly, transcribed rather unreflected here:
The average number of protesters per location is below 10 percent of the workers. And that is IIRC not counting the part timers hired for Christmas. Sure, all VerDi members might be on strike. Problem for VerDi is - most workers at Amazon Logistics are not premium payers<<<members of that funny lil pseudo-union.
VerDi needs a "success" and his boss a few strokes for his ego so they go up against the "evil capitalist from the USA". Too bad that they attack Amazon LOGISTICS, a company that pays well above the labor contract for the logistics industry. A LOUSY contract but one haggled out by - VERDI.
So now VerDi tries to put Amazon Logistics into the "Versandhandel" and force AL to accept that contract payments. And Amazon says "Thanks but no thanks". Rightly since the majority of work AL does is "take stuff from storage, put in package, put package in truck" - simples form of logistics (with matching quality of education in many workers)
The RIGHT think for VerDi to do would be to improve the LOGISTIC Workers labor contract. Sadly THAT would put them in serious problems with some very big and powerful GERMAN companies and those might take a VERY close look at VerDi and it's "Tariffähigkeit" that is wether VerDi is actually a proper representation of the workers / the proper contract partner.
This is basically VerDi's equivalent to a "Banzai Charge". If they fail at least the current leadership will suffer a "sudden illness" - not that it would hurt Verdi to get rid of the old ÖTV and postal union parasites.
