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 May 2012 the coverage rate (share of national collective agreements in force for the wage setting aspects) was 71.0 per cent in terms of employees and 67.2 per cent in terms of the total amount of wages.
In May 2012 the hourly wage index was unchanged compared to the previous month while the per employee index increased by 0.1 per cent compared to the previous month. Compared with May 2011 the hourly wage index was increased by 1.4 per cent and he per employee index was increased by 1.5. During the period January-May 2012 both indices increased by 1.3 compared to the same period of the previous year.
