The Company SC OMV Petrom SA signed a collective agreement with National Union Petrom-Energie Federation excluding arbitrarily the other industry-level union, namely Federatia Sindicatelor Libere si Independente ENERGETICA. Such an agreement changed the definition of “representative trade union” designing it in order to discriminate against both the members of the non-signatory union and the union itself. In fact, the new collective agreement provided exclusive wage increases, financial incentives and preferential shift systems reserved to workers affiliated with the signatory union and other provisions discriminating against the non-signatory union, denying its access to relevant documents and participation in various committees at the enterprise level.
