The European Union was established to promote social-political, economic harmony and fight againt all forms of social exclusion and discrimination among European countries. European union institutions employ thousands of people from all EU member countries and its the attractive job option for the many because of the numerous benefits it provides its employees. The tenents of the European Union is to fight againsts all forms of discrimination and injustice among others, but there have been concerns raised about lots of disrminations against staffs who work with these European Union instititions contrary to what its meant to fight for. The main objective of this master thesis therefore was to assess the nature and functioning of the European Union institutions. The focus was to examine some case laws on discrimination and the lack of transparency in the European Unions' institutions againt their employees. We therefore analysed some cases that was brought to the Civil service tribunal for arbitration. From the cases we analysed, it was was revealed that the European Union institutions were not transparent and fair in their civil servants' right protection. This made employees to resort to the civil service tribunal for settlements.
