Many companies took advantage of the 2013 labour reform by giving precedence to company agreements over sectoral agreements to avoid the application of the principle of correspondence in labour law (which requires that an agreement can only apply to companies where negotiators are represented) and impose less favourable conditions on workers in all their workplaces, after negotiating only with those who were often “yellow unions”. Finally, the recent regulation of the People`s Party government (Law 3/2012) facilitates the annulment of collective agreements by companies. It allows companies to unsubscribe from collective bargaining if the company records a decline in revenue or sales for six consecutive months. In addition, the law allows employers to unilaterally change wages for technical or organizational reasons. As far as the Confederation is concerned (i), this type of agreement is applicable as soon as the termination of the employment contract takes place. .
