The specially created integrated NICA's electronic database of the collective labour agreements at various bargaining levels received from the Executive Agency 'General Labour Inspectorate (EA GLI) is the main source of information used for the preparation of this section. Under the new rules for the provision and exchange of information between NICA and GLI, NICA has access to the Register of Collective Labour Agreements of GLI, and the information on the registered collective labour agreements and annexes is to be provided to NICA both electronically and in paper form. The data of the Executive Agency "General Labour Inspectorate" related to the number of employees and the code of economic activity of enterprises, as well as the data from the Commercial Register, National Statistical Institute, etc. are used as an additional source of information. The concluded collective labour agreements and annexes by economic entities, including at enterprise, industry, branch and municipality level are registered into the integrated database of NICA. The indicators used to describe the number and changes in the structure of collective labour agreements in the country include as follows:
1. Total number and dynamics of collective labour agreements;
2. Distribution by levels of bargaining;
3. Distribution by economic sector/industry/branch;
4. Territorial distribution;
5. Distribution by types of enterprises;
6. Distribution by the duration of the contracts, etc.
In order to characterize the above indicators, measurable units have been used, such as the total number, relative share, rate of changes of collective agreements and their annexes. The analysis of indicators is based on a comparison with previous periods, thus monitoring the amendment of collective agreements and annexes based on analytical groupings in terms of dynamics and statistical measurement. On this basis, conclusions and findings can be drawn about the trends, average values, distribution of collective agreements, etc. which are included in the NICA’s reports.
The grouping of collective labour agreements by the level of bargaining, territorial indication and the economic sector has been applied to NICA since the beginning of 2009. As a general rule, the information is revised every year, given the certain delay in the collection of collective labour agreement (which respectively have not been included in databases for previous periods). It should be borne in mind that few of the copies of collective agreements and annexes received in NICA lack specific dates for the signing, entry into force and/or period of duration. In such cases, the integrated database automatically calculates the duration of collective bargaining by an estimating by analogy based on the maximum period of duration up to 2 years under the Labour Code. There are collective labour agreements and annexes thereto which arrangements related to the term of duration or other terms exceed or are below the statutory established rates, for example such deviations concern the maximum duration of the collective labour agreement or the automatic extension of the duration exceeding the statutory limits. These arrangements are deemed to be valid up to the extent of the statutory provisions, and where appropriate, the deviations are demonstrated. In some cases, the parties used a copy of collective agreements at industry/branch/municipality level as a collective labour agreement concluded between them. Sometimes, incomplete or illegible copies of the contracts are provided (these are limited cases) and therefore, new copies of the collective agreements and/or their annexes are requested in order to fill in the necessary information.
