What is a posted employee?

A posted employee is any employee who usually works abroad and who carries out his work on the territory of the Grand Duchy of Luxembourg, for the limited period determined stipulated in a specific services assignment, for which a services contract has been concluded.

The limited duration is assessed in the light of the duration, frequency, periodicity and continuity of the services and in relation to the nature of the business of the posting.

As such, a company whose registered office is established abroad can, temporarily post employees for a specific mission within the framework of a transnational services project to an entity for services located in the Grand Duchy of Luxembourg.

To whom do the posting rules apply?

The rules on posting apply to companies whose registered office is established outside the territory of the Grand Duchy of Luxembourg and which, in the context of a transnational services, post an employee to Luxembourg, excepting only the maritime merchant marine sector.

Under what conditions is a posting possible?

An enterprise may temporarily post an employee to the territory of the Grand Duchy of Luxembourg, provided that an employment relationship exists between the enterprise and the posted employee during the period of posting.

When can a posting be made?

Posting can be achieved:

  • within the framework of a contract for the provision of services concluded between the sending company, established outside the territory of the Grand Duchy of Luxembourg, and the recipient of the provision of services established or carrying out its activity on the territory of the Grand Duchy of Luxembourg;
  • in an establishment belonging to the sending company or in a company belonging to the group to which the sending company belongs;
  • by a temporary employment agency or by an undertaking which, in the context of a temporary loan of labour, makes an employee available to a user undertaking established or carrying out its activity in the territory of the Grand Duchy of Luxembourg.

What about posting for temporary work agencies or companies that post their employees as a temporary loan of labour?

A temporary employment company or an undertaking which is established outside the territory of the Grand Duchy of Luxembourg and makes an employee available as a temporary loan of labour, may post an employee to a customer established outside the territory of the Grand Duchy of Luxembourg and temporarily carry out an activity on national territory, provided that an employment relationship exists between the temporary employment company or the undertaking which makes an employee available as a temporary loan of labour and the seconded employee during the period of secondment.

Secondments must take place under a contract for providing services relating to a specific purpose or activity limited in time and ending with the performance of the purpose of the contract.

What about doubts as to the reality of a posting or as to whether a company carries out a real and substantial economic activity in its country of origin?

When there is a doubt as to the reality of the posting or as to whether a company operates a real and substantial business in its country of origin, ITM carries out an overall assessment of all the factual elements it deems necessary.

Failure to comply with one or more of these assessments of factual elements shall not automatically result in the situation being de-classified as a posting. The assessment of these elements shall pertain to each individual case and shall take account of the particular features of the situation.,

Where, following the overall assessment, it is established that the employee has been wrongly or fraudulently posted, that employee shall be subject to all the laws, regulations or administrative provisions and to those resulting from collective agreements deemed to be generally binding or from an inter-industry social dialogue agreement deemed to be generally binding, in the field of work and employment.

What are the rights of a posted employee?

For the period of secondment, any seconded employee must be paid at least the standard minimum social wage in Luxembourg, or the wage corresponding to the generally binding collective agreement applicable to the activity carried out by his employer, i.e. the seconding company, as well as all the wage components laid down by a legal, regulatory or administrative provision, or by a generally binding collective agreement or by a generally binding agreement on interprofessional social dialogue, and the automatic adjustment of the wage to changes in the cost of living

ATTENTION: The automatic adjustment of wages to changes in the cost of living applies, for posted employees, only in relation to the legal minimum social wage or in relation to the minimum wage rates applicable in the sector, branch or profession by application of a generally binding collective agreement.

In addition, employers shall comply with all Luxembourg legislation concerning Sunday work, legal holidays, days off, collective leave, protection of young employees, pregnant workers, workers who have recently given birth or are breastfeeding, rest periods, health and safety at work, occupational medicine, etc.

Employees are entitled to allowances or reimbursement of expenses to cover travel, accommodation or food expenses incurred by the employee away from home for work reasons. National rules apply to the employee’s accommodation when the employer provides accommodation for employees away from their usual place of work.

What is the maximum duration of a posting?

The company can post employees for a maximum of 12 months.

A company which posts an employee to the territory of the Grand Duchy of Luxembourg for a period of more than 12 months is subject, as from the 13th month, to all the legislative, regulatory or administrative provisions as well as those resulting from collective agreements deemed to be generally binding or from an agreement on interprofessional social dialogue deemed to be generally binding, in the field of work and employment, with the exception of the procedures, formalities and conditions governing the conclusion and termination of the employment contract, including non-competition clauses and supplementary pension schemes.

If a seconded employee is replaced by a different seconded employee performing the same task at the same location, the duration of the secondment of 12 months shall correspond to the cumulative duration of the secondment periods of each of the seconded employees concerned.

The concept of “same work at the same place” is determined by assessing the nature of the services to be provided, the work to be performed and the address or addresses of the work place.

The 12-month period may be extended to 18 months upon duly substantiated notification by the company, sent to ITM on the electronic platform intended for this purpose before the 12-month period elapses.

What about initial assembly or first-time installation work?

In the case of the posting of employees in connection with work on the initial assembly or first installation work which forms an integral part of a contract for the supply of goods, which is essential for the functioning of supplied goods and which is performed by skilled or specialised employees of the supplier, the provisions concerning the minimum social wage, the automatic adjustment of the wage to changes in the cost of living and paid leave shall not apply, provided that the duration of the work in question does not exceed eight calendar days.

The eight-day period of secondment is calculated over a reference period of 12 months. When calculating this period, the duration of a secondment completed by an employee replacing a seconded employee is taken into account.

Please note that this exemption does not apply to activities in the field of construction that involve the construction, restoration, maintenance, alteration or demolition of structures, including the following:

  • excavation;
  • earthwork;

  • repair;
  • dismantling;
  • demolition;
  • maintenance;

What about expenses related to the posting?

Allowances directly related to the secondment are considered to be part of the compensation of seconded employees, insofar as they are not paid as reimbursement of expenses actually incurred as a result of the secondment, such as travel, accommodation or food expenses. The company posting employees to the territory of the Grand Duchy of Luxembourg reimburses these expenses to the posted employees concerned.

All allowances directly linked to the posting shall be considered reimbursement of expenses actually incurred as a result of the posting, unless the terms and conditions of employment laid down by laws, regulations or administrative provisions or by those resulting from collective agreements deemed to be generally binding or from an agreement on interbranch social dialogue deemed to be generally binding to the employment relationship determine which elements of the allowances are for reimbursement of posting expenses and which form part of the remuneration.

The allowances or reimbursement of travel, accommodation or food expenses apply only to expenses incurred by the employee as a result of his secondment when he has to travel to or from his usual place of work in the territory of the Grand Duchy of Luxembourg or when he is temporarily sent by his employer from this usual place of work to another place of work.
