The index of wages according to collective labour agreements measures the evolution of wages and salaries (per employee or per hour) determined by contractual provisions set by collective agreements; the indices are calculated with reference to the fixed employment structure of the base period (December 2005).
At the end of December 2011 the coverage rate (share of national collective agreements in force for the wage setting aspects) was 68.6 per cent in terms of employees and 63.1 per cent in terms of the total amount of wages.
In December 2011 the per hour index was unchanged compared to the previous month, while the per employee index increased by 0.1 per cent.
Compared with December 2010 per hour index increased by 1.4 per cent and the per employee index increased by 1.5 per cent. The 2011 early average both the hourly wage index and the index per employee increased by 1.8 per cent.
