Mr Werhof claimed that he should get the benefit of a 2.6% wage increase under a 2002
collective agreement between
IG Metall and AGV, the Nordrhein-Westfalen Metal and Electricity Federation from Freeway KG, his employer since 1999. Freeway was not a member of AGV, and in 2001 had got Mr Werhof to sign an agreement waiving all individual employment rights to wage increases that he could claim under the prior collective agreement in return for a one off wage payment under a new collective agreement with their present workforce. Freeway KG had previously been
DUEWAG AG, which was transferred to Siemens and then became separate, though DUEWAG AG had been a party to the industry collective agreement of AGV. Mr Werhof claimed that he was entitled to the wage increases as updated in the collective agreement, which had transferred to his new employer under the
Bürgerliches Gesetzbuch §613a(1), or alternatively under the EU
Business Transfers Directive. ==Judgment==
