4. Greece, Spain and Portugal have radically reformed their collective bargaining systems as part of the Year of Data Observation (see Box 2.4). The figures may therefore reflect a mixture of the legacy of the previous system and the early effects of the new system. Following the Portuguese labour market reform, which introduced significant changes in the way collective bargaining was operated in 2012 (largely reversed since then), which has made administrative renewal rules more rigid, the extent of the decline in collective agreement coverage has been the subject of much discussion. Despite good and detailed data (Quadros de Pessoal, Personnel Records, a mandatory survey of all companies, which is carried out every year in October), the calculation of the tariff guarantee is not simple, as it requires a number of assumptions. Registered agreements could be concluded by trade unions, but they could also be concluded by individual employers who work either with a group of workers or with separate workers. Agreements are often seen as the result of negotiations, but there are few signs of negotiation with non-union agreements or labour ACCORDS. These are generally standard agreements that are proposed at the signature of each worker and, in fact, the current case law ratifies the practice of offering new employees an AWA as a condition of their employment (Mitchell et al., 2005). The most recent legislation further relaxes the requirements for procedures for reaching an agreement. Collective agreements, which included both trade union and non-union agreements, have traditionally been registered with the AIRC, but after 1996, a new body, the Office of Labour Lawyers (OAS), was created to register A.A. and this body has now been given the responsibility of submitting all agreements.
OECD countries could also subject the extension of collective agreements to a public interest review that could refuse extensions if social and economic conditions did not justify extending the conditions beyond the signatory parties or, on the contrary, being adopted to protect the public interest (for example. B to stabilize the collective agreement system or avoid parasitization in mutual funds such as training). As stated in the OECD (2017, the exact definition may vary, but it is important that public interest criteria be announced by the government in a timely manner to allow social partners to take this into account in negotiations).
