Employees.

Excluded are:

Occupations

Occupations are not recorded.

Concepts and definitions

Employment

Data are collected on employees during the reference year. A distinction is made between wage earners and salaried employees, and between full-time and part-time workers; in each of these categories the data are collected according to sex.

Employees are all persons with a contract of employment with the enterprise or establishment, and who are paid a remuneration, irrespective of the nature of the work performed, the number of hours worked or the duration of the contract (fixed-term of permanent).

Wage earners are all manual workers with a contract of employment, who are remunerated either at piece rates or on the basis of an hourly or daily wage; wage earners who are paid by the month are also included in this category provided they are engaged in manual work only.

Foremen and supervisors are excluded from the wage earner category even if they are paid on the basis of an hourly or daily wage.

Salaried employees are all employees not counted as wage earners and who have a contract of employment. They include foremen, supervisors, engineers, executives as well as the managerial staff of the establishment.

Apprentices are persons who do not yet participate fully in production and who work under a vocational training contract, i.e. under conditions in which vocational training predominates over productivity.

Full-time workers (wage earners and salaried employees) are those who work at least 35 hours a week. The data refer to the average number of full-time employees registered on the payroll at the end of each month and who have been paid a remuneration.

Part-time workers are those whose regular working hours are shorter than the weekly or monthly working hours customary in the establishment. This definition covers all part-time workers, irrespective of the form of time schedule (half-day, one, two or three days a week, etc.). The number of persons working part time (by category and sex) corresponds to the annual average of persons according to the number of hours worked per week. The annual average is calculated by adding the number of persons registered at the end of each month and dividing the figure thus obtained by 12.

Labour cost

This represents total expenditures on wages and salaries and employers' social security contributions in respect of their employees in the course of the reference year. A distinction is made between expenditure in respect of wage earners and salaried employees. The following components are identified separately: Direct wages and salaries: total amount of remuneration and other regular payments made each pay period, including:

Bonuses and gratuities not paid each pay period:

Remuneration for time not worked: payments for statutory, collectively agreed or voluntarily granted paid leave, public holidays and other days remunerated but not worked, for personal or family reasons, absence on trade union activities, civic leave, etc.

Redundancy, severance and termination pay: payment in lieu of notice, for voluntary departure, etc.

Payments in kind:

Statutory social security contributions paid by the employer, after deduction of all subsidies, where such are granted:

Collectively agreed, contractual or non-obligatory contributions paid by the employer in respect of employees:

Direct social security benefits:

Cost of vocational training:

Other costs:

Less

Quantitative data are also collected separately on the costs for temporary workers:

Hours of work

The survey covers: hours actually worked during the year, reported separately for wage earners and salaried employees, full-time and part-time employees (excluding apprentices).

For full-time wage earners and salaried employees, the hours actually worked correspond to:

after deduction of

For part-time workers, the number of hours actually worked represents the average number of hours of work per week for a part-time employee as applied to the majority of employees of the establishment. This corresponds to the theoretical number of hours worked annually per employee, after deduction of paid vacation, public holidays, days of sickness and special leave granted on a statutory, collectively agreed or non-obligatory basis.

International recommendations

The definitions of labour cost and of hours actually worked correspond to the current international recommendations.

Classifications

Components of labour cost / compensation of employees

The data on labour cost are classified by groups of components (see above, under Concepts and definitions). This classification is linked to the International Standard Classification of Labour Cost (1966).

Industrial

The data on labour are classified in accordance with the Standard Classification of Economic Activities of the European Communities (NACE), 1990, Rev.1, which is compatible with the International Standard Industrial Classification of All Economic Activities (ISIC), Rev.3, 1990.

Occupational

Not relevant.

Others

The data on labour cost are also classified by size of establishment (10 to 49 employees, 50 to 199, 200 to 999 and 1000 and more employees) and by worker category (wage-earners and salaried employees).

Sample size and design

Statistical unit

The survey unit on which data are collected is the establishment.

If an enterprise consists of more than one establishment and failing adequate accounts, it may supply the information requested by applying distribution ratios, established on the basis of direct wages or number of employees.

Survey universe / sample frame

The sample frame is the directory of enterprises compiled by the STATEC. This directory is continually updated on the basis of the administrative records relating to value added tax (VAT) and social security institutions.

Sample design

The survey is based on a complete enumeration of all enterprises covered by the survey. In 1992, the sample comprised 1,850 establishments.

Field work

Data collection

The survey is conducted by post. A questionnaire is sent out in the spring following the reference year.

Survey questionnaire

The questionnaire seeks information on:

as well as the identity of the person from whom supplementary information can be obtained. An explanatory note provides detailed instructions concerning definitions, inclusions and exclusions.

Substitution of sampling units

Not relevant.

Data processing and editing

The data are stored on micro-computer by means of a BLAISE (CAPII) software programme, with filters and plausibility checks. Clarifications are obtained by telephone, and repeated reminders are sent. The enterprises surveyed are legally obliged to reply to STATEC questionnaires.

Types of estimates

The aggregated results are obtained by weighting, using as weights the number of hours actually worked.

Construction of indices

None.

Weighting of sample results

Not relevant.

Adjustments

Non-response

Missing data are imputed on the basis of replies from similar enterprises, or by reference to the annual survey on industrial production.

Other bias

Not relevant.

Use of benchmark data

Not relevant.

Use of other surveys

The survey results are compared with those of the six-monthly survey on earnings and the annual survey on industrial production.

Indicators of reliability of the estimates

Coverage of the sampling frame

The STATEC register of enterprises is assumed to cover all enterprises and establishments included in the survey coverage.

Sampling error / sampling variance

Not relevant.

Non-response rate

About five per cent.

Non-sampling errors

No estimate is made.

Conformity with other sources

Not available.

Estimates for non-survey years

These estimates are required by the Statistical Office of the European Communities (EUROSTAT) and compiled as follows for each year between survey years (the following example applies to 1989):

C89 = (s89/s88) * W88 * (1 + K89),

where,

C89 = cost updated for the year 1989,

s89 = average hourly (monthly) earnings in 1989,

s88 = average hourly (monthly) earnings in 1988,

W88 = average hourly (monthly) earnings in 1988 from the last survey on labour cost,

K89 = updated average proportion of additional costs for the year 1989 (additional costs/direct wages).

s89/s88 gives the rate of increase in earnings according to the six-monthly harmonized survey on earnings.

(1 + K89) is a coefficient of the updated cost structure. If the weight of the additional costs in relation to direct earnings has varied because of changes in legislation or collective agreements, the estimates take this into account.

Available series

The level (hourly and monthly cost per employee) and structure of labour cost (by branch of economic activity and by labour cost component).

History of the survey

The labour cost survey began in 1973. It is part of the Community wage statistics system and is conducted under the auspices of the Statistical Office of the European Communities (EUROSTAT). Up to 1981, the survey took place every three years. Since 1984, it has been conducted every four years. The surveys for 1972, 1975, 1978, 1981 and 1984 covered industrial activities, while those relating to 1974, 1978, 1981 and 1984 covered wholesale and retail trade, financing and insurances.

The survey questionnaire is revised for every four-yearly survey, in accordance with EUROSTAT directives. The 1988 questionnaire introduced a section concerning collectively agreed, contractual or non-obligatory costs borne by the employer for the benefit of the workers. The 1992 questionnaire contained additional questions on the cost of temporary labour, and the questions on hours of work were modified. The 1992 survey was conducted in accordance with EEC Regulation No. 3942/92.
