The course in Industrial Relations Law deals with the legal and institutional aspects of collective labour relations, in particular: freedom of association and trade union organisation, collective agreement and collective bargaining, workers' representatives in the workplace and their rights, the right to strike. These macro-themes are addressed in the light of the relevant constitutional and international principles as well as the private criteria used to interpret/apply the collective agreement in our system. Particular attention is paid to the theoretical approach that sees in the rules concerning collective labour relations an eminent manifestation of collective autonomy. The legal source will be examined with regard to the legislative discipline supporting trade union activity in the workplace (Workers' Statute), as well as the two laws of 1990 and 2000 on the limits to strikes in essential public services, and the most recent legislative interventions on proximity collective bargaining and tax incentives for collective agreements that provide for productivity bonuses or company welfare measures.
