An increasing number of German employees are working abroad, and more foreign workers are temporarily employed in Germany. These employees need documentation to apply for jobs overseas. Therefore, upon request, they should be provided with an English version of their work reference in addition to the German one. The practical guide offers valuable assistance in this regard. The authors first explain the content and legal aspects of references, as well as reference and recommendation letters, and also address the specific issues that arise when using references internationally. There is also a need in other countries to obtain information about applicants from previous employers. Therefore, it is helpful to include English-language references in one's application documents, even when this is generally not required in the country of application.
