🟠 Oltre il traguardo: guidare il cambiamento attraverso l’inclusione.
In un mondo industriale che evolve, non basta più essere produttori di eccellenza. Dobbiamo essere ambasciatori di valori.
Oggi celebriamo un momento fondamentale per il nostro Gruppo: STM SpA ha superato con successo l’audit per il mantenimento della Certificazione per la Parità di Genere e ha condiviso questo percorso con le sue consociate. GSM SpA e Neri Motori Srl, infatti, hanno oggi raggiunto lo stesso traguardo, ottenendo la loro prima Certificazione UNI/PdR 125:2022.
Per noi, la parità di genere non è un punto d’arrivo, ma un asset della nostra visione presente e futura.
Come Gruppo, vogliamo infatti trasmettere:
- Responsabilità: essere pionieri di una cultura dove il talento non ha genere.
- Visione: costruire un ambiente di lavoro che sia lo specchio della società inclusiva che vogliamo per le prossime generazioni.
- Impatto: dimostrare che l'inclusività è un motore di innovazione e crescita sostenibile.
Siamo orgogliosi di promuovere messaggi positivi che vadano oltre i cancelli delle nostre aziende.
Il successo di GSM e Neri Motori, che hanno ottenuto la loro prima certificazione seguendo il percorso della capogruppo, è la prova che il cambiamento è reale quando diventa una missione collettiva.

🟠 Beyond the finish line: driving change through inclusion.
In an evolving industrial world, being producers of excellence is no longer enough. We must be ambassadors of values.
Today, we celebrate a pivotal milestone for our Group: STM SpA has successfully passed its maintenance audit for Gender Equality Certification and has shared this journey with its subsidiaries. Indeed, GSM SpA and Neri Motori Srl have reached the same goal today, obtaining their first UNI/PdR 125:2022 Certification.
For us, gender equality is not a finish line, but a core asset of our present and future vision.
As a Group, we aim to convey:
- Responsibility: being pioneers of a culture where talent has no gender.
- Vision: building a workplace that mirrors the inclusive society we want for future generations.
- Impact: demonstrating that inclusivity is a driver of innovation and sustainable growth.
We are proud to promote positive messages that extend beyond our company gates.
The success of GSM and Neri Motori, who achieved their first certification by following the path set by the parent company, is proof that change is real when it becomes a collective mission.
