A1 certificate

Since 2010, employees need an A1 certificate for every trip abroad within the EU - but only recently has control been introduced. If you don't have an A1 certificate printed out with you, you run the risk of being refused entry to the country, admission to hotels, science fairs, conferences, etc. In the worst case, a cash fine is due immediately, the ZMT must pay a fine, and/or the social security contribution must be paid again/double.

This EU Regulation (EC) Nr. 883/2004 on social security has been in force since 1 May 2010 and coordinates the social security systems of the member states of the European Union. It applies to all EU countries as well as Iceland, Liechtenstein, Norway and Switzerland. Since this regulation came into force, anyone temporarily employed in an EU member state must carry an A1 certificate - regardless of how long they have been working there.

How to proceed (please, two weeks in advance):

  1. Filling out the business trip application form
  2. Fill out the the questionnaire for the application for A1 certificate (download here)
  3. Submitting documents to the Travel Management
  4. Final clarification and submission of the application by Nele Witt
  5. Notification of A1 certificate issued by Mrs Witt to the traveller

How do we want to shape our research and related activities to do better in the future?

Letter of recommendation

Letters of recommendation are available for various occasions. For example, you can include them as a reference in your own application. Students who want to enrol for a Master's after their Bachelor's degree are also asked by the university to submit a letter of recommendation from a former lecturer or professor. A letter of recommendation is written in the first person form. This is why letters of recommendation are much more personal than a testimonial. In terms of content, it is mainly about the skills and expertise of the person described - and about their personality. A letter of recommendation contains among other things Name and address of the addressee (not that of the applicant), subject ("Letter of recommendation for Max Mustermann"), self introduction (short), reason for the exhibition (e.g. end of internship), objective recommendation, qualifications achieved (e.g. degree), successes, subjective recommendation (soft skills, character). The letter of recommendation can be prepared by the supervisors.

Parental leave

After the birth of a child, both parents are entitled to a three-year leave from work, the parental leave.

Preventive medical check-up

Everyone who works at ZMT and travels for ZMT has the obligation to undertake medical precautions for this. Each traveler is responsible for registering for the screening himself/herself. Registrations go to the company doctor (see Company medical officer). A preliminary appointment of at least 4 weeks before travel starts is appropriate. ZMT covers the costs for a preventive medical check-up. A cost assumption declaration can be obtained from the HR Management.


Promotional material

Advertising material, such as flyers and brochures, can be distributed to project partners or displayed at events. Small give-aways with ZMT logo can also be used. The materials currently available can be obtained from the PR department.

Contact: Andrea Daschner


Proof of employment

With the proof of employment, the employer certifies an existing employment with the employee. It serves as proof that the employee is currently employed by the employer. It contains, for example, information on the type of work, contract duration, salary and working hours. Further information can be obtained from HR Management.



Reimbursement of expenses

Expenses are an exception! Each procurement has to take place according to the procurement guidelines given by the country of the central purchase! If, as an exception, a procurement cannot be carried out by the purchasing department, the expenses can be reimbursed. The appropriate reimbursement form is in the Intranet Service Point > Printable Forms > Business trips


Right of Appeal

According to §13 AGG (Chapter 3 / Section 13 General Anti-Discrimination Act) every employee shall have the right to lodge a complaint with the competent department in the firm, company or authority when they feel discriminated against in connection with their employment relationship by their employer, superior, another employee or third party on any of the grounds of race or ethnic origin, gender, religion or belief, disability, age or sexual orientation. The complaint shall be examined and the complainant informed of the result of the examination.

In practice, there is a risk of conflicts of interest due to the dual mandate of the women's and the severely disabled representatives. At the same time, the works council cannot perform employer functions and is not obliged to forward the complaint. Therefore, the ZMT of the Bremer VFwF e.V. assumes the role of a complaints office.

Several meeting rooms of almost any kind and size are available at ZMT, which can be reserved. The easiest way is to reserve a room on the Intranet. (Home > Room reservation)

Sustainability @ Leibniz

Sustainability is an important guiding factor for the Leibniz Association and its member institutions. As a research organisation, the Leibniz Association contributes to sustainable development in the fields of research and knowledge transfer, as well as through its management and operations. The political frame of reference is provided by the 17 UN Sustainable Development Goals (SDGs), which guide the Leibniz Association’s actions – through sustainability research and through sustainable research processes and operations.

=> Sustainability Mission Statement: The Sustainability Mission Statement provides a framework for a ‘culture of sustainability’ in the Leibniz Association and its member institutions – a culture that must be established and continuously built on within the various spheres of activity. The mission statement is also intended to encourage the employees of the Leibniz institutions to reflect on their actions and to contribute to the sustainable development of the association.



Every employee is entitled to a testimonial. A testimonial must only be issued if the employee requests it. However, the employer is always obliged to issue the certificate when a apprenticeship is terminated. Trainees do not have to request this first.

Testimonials can vary in scope. This depends on the duration of the employment and the wishes of the employee. The simple testimonial contains personal data as well as type and duration of employment. Activities must be described so completely and precisely that future employers can form a clear picture. However, no assessment of performance is made. The reason and circumstances of the termination of employment may only be included in the testimonial at your request. The qualified testimonial will also describe performance and behavior. Employees are entitled to the qualified testimonial after a relatively short period of employment if a rough assessment of their professional and personal abilities is already possible. According to the courts, this is usually the case after a few weeks. Employees can choose between a simple or a qualified testimonial.
