Does my code decide a collective agreement or social security status?

No. A NACE code does not decide collective agreement coverage, and it does not decide social security status. A code is a statistical classification of an economic activity, and the EUR-Lex summary states that the legislation only applies to the use of the classification for statistical purposes. A collective agreement is an agreement between employers and workers, or their organisations, that sets terms and conditions, and its coverage is decided by the agreement itself, by the law that governs it, and by the facts about the employment relationship.

Social security status is decided under social security law, on the facts about the person, the employment, and the contributions, by the social security body. Neither is decided by a statistical code, and a reader who treats a code as a decision on either question confuses a category with a legal status.

What decides collective agreement coverage?

Collective agreement coverage is decided by the agreement, the law, and the facts. An agreement can define its scope by activity, by sector, by employer, by occupation, or by other criteria, and the scope must be read in the agreement text, not inferred from a code. A statistical code can be used as a descriptor in an agreement, or in the statistics about an agreement, where the agreement or the statistics state that they use it, but the code does not create the coverage, and a change of code does not, by itself, change the coverage. A worker’s coverage depends on the employment relationship, the employer, and the agreement that applies to that relationship, as determined under the law that governs agreements in the country concerned. A reader who needs to know whether an agreement applies should read the agreement, and should ask the employer, the worker organisation, or the body that administers agreements, with the facts about the employment, rather than quoting a code as if it answered the question. This site does not give advice on collective agreements, and it does not determine any reader’s code.

What decides social security status?

Social security status is decided under social security law, on the facts about the person and the work: whether the person is employed, self employed, or in another status recognised by the law, what contributions are due, and what benefits follow. The social security body decides the status, on the evidence it requires, and the decision is recorded in the social security record, not in the statistical register. A statistical code can appear in a social security record as a descriptor of the employer’s activity, for statistical purposes, without deciding the status of any individual. A change of code for the employer does not, by itself, change the status of a worker, and a worker’s status does not change the employer’s code. The two records are different, they are held by different bodies, and they are decided under different laws. A reader who needs to know a social security position should ask the social security body, with the facts about the person and the work, and should not rely on a code for the answer.

Why do codes appear in employment and social security contexts?

Codes appear in employment and social security contexts because those systems need to group employers and employments for statistics, for administration, and for analysis, and a statistical code is a convenient grouping attribute. A social security return can ask for the employer’s activity code, an employment survey can break its results down by NACE section, and a collective agreement database can group agreements by sector, without the code deciding any individual case. The grouping use is statistical and administrative, and it should be read as such. A code in a grouping is a label for a set of employers or employments, and it does not state the position of any one employer or worker in the set. A reader who reads a grouping label as a decision about a named person treats an aggregate as a finding, and the treatment should be corrected by opening the record for that person, held by the body that decides the status.

Question	Decided by	Record
What activity category?	Eurostat, explanatory note	Note, version stated
What code is held for the unit?	Institute or business register	Register entry, identifier, version, date
Does a collective agreement apply?	Agreement, law, and the employment facts	Agreement text and the deciding body
What is the social security status?	Social security law and the social security body	Social security record

The table keeps the employment questions with their holders, and the code questions with theirs. A code is an answer to the second row, in part, and to the first, in general terms. It is not an answer to the third or fourth rows, and a citation that uses it as such should be corrected.

What is the limit, stated plainly?

The limit is stated in the guardrail on every guide on this site: statistical classification only, no determination of any reader’s code, confirmation with the national statistical institute or the business register, and general information, not advice on any reader’s registration. The limit applies with full force to collective agreements and social security. A code does not decide coverage, status, contributions, or benefits. A change of code does not, by itself, change any of them. A code in an employment or social security record is a statistical descriptor, and its effect, if any, is governed by the law and rules of that system, not by the classification. A reader who needs an answer on either question should seek it from the body that decides it, with the facts, and should not rely on a classification guide.

Where is a code confirmed, and where is status confirmed?

A code is confirmed with the national statistical institute or the business register that holds the record, and the category meaning is confirmed in the Eurostat explanatory notes. Collective agreement coverage is confirmed with the agreement and the body that administers it. Social security status is confirmed with the social security body, under social security law. Confirm the code with the institute or register, confirm the status with the body that decides it, and keep the confirmations in separate records.
