Not every seal carries the same weight
Not every seal carries the same weight
In his Praxisleitfaden, Oliver Scharfenberg sorts employer seals into four categories by how much they actually say:
Since 27 September 2026, the EU EmpCo Directive, implemented in Germany through the third amendment to the UWG, prohibits sustainability labels without a transparent certification scheme. Whether the same standard applies to employer seals is an open legal question. Employers are already well advised to choose seals that rest on an anonymous survey of the whole workforce, external verification and a transparent catalog of criteria.
Our Connection to Employer Seals
Our Connection to Employer Seals
Syntharis Group advises employers on certification. Our CEO, PhDr. Oliver Scharfenberg, is closely involved with the Deutsches Institut für Qualitätsstandards und -prüfung (DIQP) and acts as its scientific advisor; the DIQP’s “Top Arbeitgeber” seal was the one tested in his experiment. We say this openly because a seal is only worth something if people can trust it, and the same applies to the advice about it.
