Speaking to journalists outside a Zara store in Porto, Cristina Monteiro, head of the CESP Union for Commerce, Office and Services Workers, said the Spanish Inditex group, which also owns such as Bershka and Pull & Bear, was not fulfilling a collective contract for employees in Portugal.

The union wants better wages and for timetable rules to be respected. Lusa News Agency approached Inditex for comment but none as yet has been given.
