Labour cost index in the private sector
In the inquiry for the labour cost index, data are collected quarterly from data suppliers on the size of personnel and volume of labour input, wage and salary costs, and social cost tariff or the percentage share of social security contributions of the wages and salaries sum. In manufacturing, data are broken down by form of remuneration (hourly vs. monthly paid), in service industries by part-time employment.
In most industries the sample comprises enterprises employing at least 30 wage and salary earners. In industries dominated by small enterprises (construction, wholesale and retail trade, hotel and restaurant activities, real estate activities, professional, scientific and technical activities, administrative and support services) enterprises employing at least 20 wage and salary earners belong to the population. The sample is updated annually. The size of the sample is good 2,000 enterprises.
