“…In Spain, to legitimate the production of institutional power, before and after the crisis, CCOO and UGT have made use of their dominant position in trade union elections (Beneyto et al 2016; Jódar et al 2011) and, as well, through the organisation of general strikes before and after the crisis (Molina & Barranco 2016), portraying themselves as ‘class unions’ that protected the interests of all workers and could, thus, intervene in political affairs.
