Equality and Collective Relations

Staff Representatives and Social Elections in Luxembourg

The staff delegation is the body representing employees within a Luxembourg company. It is mandatory as soon as the headcount reaches 15 employees. Elected for five years, staff representatives have rights to information, consultation and intervention on working conditions, health and safety, and equality matters. This guide sets out the electoral rules, eligibility conditions, how the delegation is organised and its specialist roles.

Legal basis: Art. L.413-1 to L.413-4; L.414-9; L.414-14; L.414-15; L.416-1; L.432-46 Updated: June 2026

1. Workforce threshold and obligation to establish a delegation

Any employer with at least 15 employees in Luxembourg is required to hold social elections and establish a staff delegation. The threshold is assessed on the basis of the number of employees actually employed in the company or establishment.

The number of representatives to be elected increases with the headcount, according to a scale set out in Art. L.413-3 of the Labour Code. Each full member has a corresponding substitute who sits in their absence and may permanently take their seat if the mandate ends early.

The Labour and Mining Inspectorate (ITM) is the competent authority for overseeing the proper conduct of the electoral process. In the event of a dispute over the regularity of proceedings, any interested party may refer the matter to it.

The obligation to establish a staff delegation is separate from the requirement for a joint works committee, which is only required from 150 employees. Both bodies coexist in companies reaching that second threshold, with complementary but distinct roles.

2. Organisation of elections and voting system

Secret ballot and candidate lists

Social elections are conducted by secret ballot. The general rule is proportional representation, which applies in companies with 100 or more employees. In companies with fewer than 100 employees, a relative majority system is used (Art. L.413-1).

Candidate lists may be submitted by two types of actors:

a trade union with national general representativeness (Art. L.161-4) or sectoral representativeness (Art. L.161-6);
a group of employees representing at least 5% of the total workforce, up to a maximum of 100 persons (Art. L.413-1).

Election by default

If the number of candidates does not exceed the number of seats to be filled and all candidates agree on the allocation of full and substitute mandates, they are declared elected by default without any need to proceed to a vote (Art. L.413-1). This simplified procedure is common in small and medium-sized companies.

If no list is submitted within the prescribed deadlines, the Labour and Mining Inspectorate conducts an inquiry. Representatives may then be designated by ministerial order (Art. L.413-1). The absence of candidates does not relieve the employer of their obligations regarding staff representation.

3. Eligibility and electorate

Conditions to stand as a candidate

To be eligible, an employee must meet three cumulative conditions assessed on the date of election (Art. L.413-4):

1be at least 18 years old;
2have at least 12 months' seniority in the company, prior to the first day of the month in which the notice announcing the elections is posted;
3be a Luxembourg national or authorised to work on Luxembourg territory.

Functions excluded from eligibility

Certain persons are explicitly excluded from the right to stand, due to their hierarchical position or connection to management (Art. L.413-4). The following may not be elected:

managers, directors and the head of the HR department;
relatives by blood or marriage up to the fourth degree of the head of the company.
The right to vote (electorate) is separate from eligibility conditions (candidacy). As a general rule, all employees of the company with a certain level of seniority may vote, including those who cannot stand as candidates. The precise conditions for the electorate are set out in Art. L.413-5 and following.

4. Mandate, constitution and executive committee

Length of mandate

The mandate of staff representatives lasts five years. Outgoing members may be re-elected with no limit on the number of consecutive mandates (Art. L.413-2). The mandate ends automatically on termination of the employment contract, resignation from the mandate or removal under the conditions provided by law.

Constituent meeting

Within the month following the elections, the delegation holds a constituent meeting at which it designates by secret ballot, by relative majority:

a chairperson, a vice-chairperson and a secretary;
an executive committee whose size varies according to the number of full members: 1 additional member for a delegation of 8, up to 4 additional members for a delegation of 14 or more (Art. L.416-1).

Transfer of undertaking

In the event of a transfer of a company or establishment, the fate of the delegation depends on whether the transferred entity retains its autonomy. If the establishment retains its autonomy, the delegation continues and carries on its functions. Otherwise, the members of the transferred delegation join the delegation of the receiving entity (Art. L.413-2).

5. Remit and specialist roles

General role: information and consultation

The staff delegation is the institutional counterpart of the employer for the defence of employees' collective interests. It has a right to information and consultation on matters relating to the organisation of work, conditions of employment, vocational training and workforce planning. These general remits are governed by Art. L.414-1 to L.414-13.

Joint agreement required from 150 employees

In companies with at least 150 employees, certain key decisions may only be taken by joint agreement between the employer and the staff delegation (Art. L.414-9). These include in particular:

the installation of employee monitoring systems;
the setting of selection criteria for collective redundancies;
the drafting or amendment of the internal regulations;
the introduction of telework.
In the absence of a joint agreement on any of these matters, the employer cannot implement the measure unilaterally. If disagreement persists, an arbitration or mediation mechanism may be invoked. Failure to comply with this joint-agreement obligation exposes the employer to sanctions and the nullity of the measure taken.

Health and safety representative (Art. L.414-14)

The delegation designates from among its members, or from among other employees, a health and safety at work representative. This representative carries out inspection rounds of working conditions, reports identified risks and collaborates with the Labour and Mining Inspectorate and the Occupational Health Service. Their role complements that of the occupational physician.

Equality representative (Art. L.414-15)

An equality representative is designated from among the full or substitute members of the delegation. Their role is to ensure compliance with the principle of equal treatment within the company, in particular regarding access to employment, vocational training and remuneration. They act as an internal point of contact for employees who believe they are being discriminated against, working alongside the health and safety representative in harassment situations.

6. Special situations

No candidates

If no list is submitted by the end of the candidacy period, the delegation cannot be constituted. The Labour and Mining Inspectorate then conducts an inquiry and may, by ministerial order, designate representatives by default from among eligible employees (Art. L.413-1). This procedure ensures that employees are not left without collective representation for an extended period.

European Works Council

In groups of undertakings of Community-scale dimension with establishments in Luxembourg, the Luxembourg representatives on the European Works Council are elected or designated by the members of the staff delegations of the Luxembourg entities (Art. L.432-46). The staff delegation therefore serves as the designating body for transnational representation.

Early termination of mandate

A representative's mandate ends before its term in the event of termination of the employment contract (resignation, dismissal, end of fixed-term contract), resignation from the mandate, loss of eligibility conditions or removal under the legal conditions. In such cases, the corresponding substitute takes the vacant seat for the remaining term. The protection against dismissal enjoyed by representatives is governed by Art. L.415-1 and following, which provide for a prior authorisation procedure before the competent court.
