Two periods can be identified in Spain's efforts to tackle the crisis. During the first period, the fundamental concern guiding the legislative response was to tackle the acute employment crisis resulting from the widespread losses of jobs, with a particular impact on the construction sector and on sectors dependent on the real estate sector. Social agreement, including wage restraint, the extension of social protection to unemployment situations and incentives for stable employment contracts were the focus of public authorities’ action from 2009 to May 2010. With ongoing job losses and the declining confidence of the financial markets in the solvency of the Spanish State, there was a dramatic turnaround coinciding with the outbreak of the Greek crisis. The economic measures being implemented in Spain since May 2010 comprise a highly varied raft of measures focussing on reducing the public deficit as the only way to put an end to the economic recession. This powerful tendency reached its peak in September 2011, when Article 135 of the constitutional text was reformed to impose the principle of bringing public authorities’ spending into line with the public debt limit laid down in the Treaty on the Functioning of the European Union.
