The unspoken rule: is English really the key to success in Europe’s boardrooms?

Around the boardroom table, Carmen-Maja Rex’s colleagues slip easily between French and English. When the Airbus CHRO takes her seat, the discussion naturally settles into English without anyone flagging the switch. For a company founded in France, built partly in Germany, assembling aircraft across Europe and flying them globally, English has quietly become the default working language. The same takes place just a few hundred kilometers away at Sodexo’s headquarters just outside of Paris. CHRO Heather Jacobs is American, and most of her conversations in the boardroom are in English, despite the company having roots in the French city of Marseille.

English is now the most widely spoken language in history, with around 1.5 billion speakers worldwide, and fluency in it has quietly become an unwritten yet essential requirement for many senior roles at multinationals. This expectation can disadvantage those who are not native English speakers, and now sits against a wider political backdrop in which leaders such as Donald Trump have designated English as the U.S.’s official language, promoting warnings from scholars about how easily the ‘speak English’ rhetoric can slide into exclusion.

The OECD examined 11 million online job postings in 2021, across the EU and the U.K., and found that 22% explicitly required English proficiency. German was the next most frequently requested language, appearing in 1.7% of listings, often in tourism-related roles. French was required in only 1.1% of postings, while Italian was required in only 0.4%.

In Europe’s boardrooms, the growing dominance of English isn’t just a matter of habit; it’s also driven by global business demands, with effects that reach into areas such as rules and safety. It also shapes who fits in, who advances, and how companies operate. The question now is whether AI is reinforcing English as a ‘superior’ language of leadership, or simply making it easier for organizations to maintain a common corporate language—and whether businesses could realistically return to a more localised way of functioning.

A language born of power, not policy

Although English is mandated as the common corporate language in many Fortune 500 Europe headquarters across the region, its dominance is, in many ways, a historical “accident”. Nina Bellak, PhD, Senior Lecturer at the University of Vienna, links the power of English in boardrooms to postwar history. “There’s this power dynamic at a national level between the colonizer and colonized, and it’s a very similar dynamic at a corporate level,” she says. Explaining that English became far more prominent post World War as U.S. economic and political power expanded across the continent.

Over the following decades, English gradually displaced local languages such as French and German as the dominant working language. Many Fortune 500 European companies have mandated English for simple operational reasons, ranging from safety standards to international financial reporting. Airbus’s decision to mandate English as its working language goes back to the company’s birth in the 1970s, says Rex. “This was very surprising, especially in those days in France—there were not many French companies [that agreed] on English [becoming] the common language,” she adds. The reasoning was largely practical: aviation safety, where English is the global standard.

Similarly, in the early 2000s, Siemens began using English more consistently after listing on the NYSE, particularly for financial communications, says Nanda Burke, global head of talent and organization at Siemens. In other cases, companies adopted English more organically. For example, at the Swiss electrification and automation company ABB, English became the common corporate language following the merger of Swedish firm ASEA and Swiss company Brown Boveri in 1988. With neither Swedish nor German able to claim precedence, English emerged as neutral ground—less a deliberate strategy than a diplomatic necessity, according to Carolina Granat, ABB’s chief human resources officer.

Beyond industry factors, the prevalence of English within Fortune 500 companies in Europe also reflects its widespread use across countries. In the Netherlands and countries in Scandinavia for example, English classes are compulsory at schools and so individuals pick up the language at a much younger age, hence often functioning as a natural second language. Kaija Bridger, EVP people & communications at elevator engineering company, KONE, says that, in Finland, where the company is headquartered, the country’s small domestic market has caused people to look outward and so most senior leaders operate comfortably in English. “Finnish wouldn’t be the most dominant language to begin with,”
