In early 2004, a group of “Designated Workers” exchanged information regarding their approach to their mission and how to organize within the company. From this reflection was born the Association of Designated Workers Luxembourg (ATDL).

The ATDL has the legal status of a non-profit association (ASBL). All activities are carried out by volunteers whose objective is non-commercial.

One of the priorities is to share each other’s experiences and offer help to members who wish to receive it.

In addition, the ATDL collaborates with the main national authorities and organizations that deal with the safety and health of workers. The ATDL is the unique and recognized interlocutor as an association of “Designated Workers” by the authorities of the country.

It was among the first to adhere to the Vision Zero charter.

Since its creation, the ATDL has been proposing modifications to competent authorities regarding the function of the “Designated Worker” within the framework of drafting future Luxembourgish laws and regulations concerning our function and Workplace Safety and Health in a general sense.

When a file (training, experience…) needs to be presented to the competent authority for approval of the appointment of a Designated Worker, the association defends the “Designated Workers” within the “Consultative Committee” for the proposals validation of the “Designated Workers”.

In the same context, the ATDL also participates in the proposal of training programs for “Designated Workers” and for continuous training, as prescribed by the Grand-Ducal regulation.

Close links also exist with other national and international associations that have similar interests.

Through its different contacts and the contribution of its active members, the ATDL also provides legal and technological support on occupational safety and health aspects.

Through this website, a LinkedIn discussion group, regular meetings, conferences, company visits, newsletters… The ATDL provides an exchange of information and ideas, in order to professionalize our mission and protect the person in their role as “Designated Worker”.

Finally, the Association wants to promote and enhance the role of the Designated Worker within their company and in relation to external stakeholders.

Together, we are stronger and less isolated, within our companies and facing supervisory bodies.
