The Labour force survey is a sample statistical survey carried out through households. The main purpose of the survey is to provide data on labour status of population aged 15 years and over and main characteristics of employed, unemployed and persons out of labour force in the Republic of Bulgaria.

In 2019 an ad hoc module on  work organisation and working time arrangements was incorporated in the regular Labour force survey. The 2019 ad hoc module provides detailed and comparable data on:

- flexibility of working time;

- autonomy of work;

- place of work and commuting time.

The classifications applied in the Labour force survey are harmonised with the international classifications in terms of economic activities, occupations, educational attainment. The main classification used are the following:               

• International Standard Classification of Education - ISCED 2011;
• Classification of Economic Activities - 2008, which is a Bulgarian version of NACE, Rev. 2 -  since 2008;
• National Classification of Occupations - 2011 (1st digit - occupational class), comparable to the International Standard Classification of Occupations – ISCO ’08 -  since 1 January 2011;
• International Classification of Status in Employment - ICSE-93;
• Classification of Territorial Units for Statistical Purposes in Bulgaria, harmonised with the European Classification of Territorial Units for Statistics - NUTS.

All persons aged 15 years and over living in the selected non-institutional households are covered by the Labour force survey. The target population for the ad hoc module "Work organisation and working time arrangements" consists of employed persons.

The main definitions applied in the survey are in accordance with the recommendation of International Labour Organization (ILO) and EU legislation.

Employed are persons aged 15 and over who during the reference period:

• performed some work for at least one hour for pay in cash or in kind or other income;
• did not work but had a job or an enterprise, a business from which they were temporarily absent due to illness, annual leave, full-paid maternity leave, parental leave, strike or another labour dispute, etc.

Professional status. According to professional status the employed persons are classified in the following categories:

• employers - persons who work in their own enterprise, business, farm, professional practice and  employ at least one other person;
• self-employed  - persons who work in their own enterprise, business, farm, professional practice and do not employ any other person;
• employees - persons who work for a public or private employer and who receive wages (salaries), fees, remuneration by civil contract etc.;
• unpaid family workers - persons who work without pay in an enterprise, farm, owned and operated by a relative of the same households.

In the tables consisting data from the ad hoc module on work organisation and working time arrangements, the employers, self-employed without employees and unpaid family workers are presented as one category – self-employed.

All variables of ad hoc module "Work organisation and working time arrangements" according Commission implementing regulation (EU) 2017/2384 of 19 December 2017  were covered.

 

The sample used for the Labour force survey is a two-stage stratified cluster sample which includes quarterly about 19.6 thousand households (representing about 0.65% sampling rate).
The ad hoc module on work organisation and working time arrangements was carried out over a part (25%) of the LFS sample in each quarter and consisted of the households from the third wave.

Due to the sampling approach used in the Labour force survey, the estimation of the parameters obtained from the survey could vary from those in the population due to sampling errors, errors due to non-response, errors in registration or processing etc.

Coefficients of variation (relative standard errors), and confidence intervals (i.e. the range of values that 95% of times would capture the true value in the population) are calculated for assessment of stochastic reliability of the estimates for main indicators.

The results from the ad hoc module "Work organisation and working time arrangements" were presented on 9 July 2020.

 

Comparability across EU Member States is considered high due to use of harmonised concepts, variables, definitions and classifications.

 

Labour force survey ad hoc module on work organisation and working time arrangements was carried out in 2004 but due to differences in the methodology used data are not comparable with that from 2019 ad hoc module.

The number of employed persons according to the ad hoc module slightly differs from the corresponding average annual data from the Labour force survey due to use of sub-sample and presence of small number of respondents, not interviewed on the ad  hoc module.

The average duration of the interview on the ad hoc module "Work organisation and working time arrangements" was about 10 minutes per person.
