[By Kees Hudig] – According to the website of the German paper FAZ, the German federal constitutional court will pass a ruling on the flash mob – a group that suddenly appears, assembled by use of the Internet or text messages – used by services union Ver.di in late 2007 in a labour conflict. This happens after the labour court ruled in September that the union had legitimately used the instrument in its struggle with supermarket chain REWE. After calls by the union in December 2007 to form flash mobs, groups of union members and sympathisers ‘raided’ a branch of the chain, quickly filling up trolleys with groceries and then leaving them in front of the checkout. Retail organisation HDE refused to accept the ruling and is now suing the union before the federal constitutional court. According to the HDE, the union engaged in ‘systematically vandalizing shops’. The organisation is particularly upset about the involvement of ‘handelsfremde Aktivisten’ (activists unrelated to the company). A Ver.di spokesman explained that this kind of new methods have to be used because the supermarket chain is employing more and more temp workers.
