Of the 1.5 billion English speakers in the world, over half learned it as a second or additional language.

The “language of business”, English has become a foundational skill for anyone looking to work in an international business or at a leadership level, and many English as a Second Language (ESL) speakers find themselves working in English on a daily basis.

But working in your second or third language comes with a unique set of challenges and opportunities.

We spoke to five global leaders about the role English has played in their careers, the challenges of being an ESL speaker, and how businesses can create a culture where everyone has a voice.

A passport to leadership

Strong English skills open doors. More than three-quarters of people with advanced English skills are in senior or leadership roles, compared to just 32% of those with limited English proficiency.

app Languages CTO, , describes English as a “passport for this new world of opportunities, opening many, many doors I wouldn’t have had access to.”

There’s a cumulative effect, with one door opening and leading to the next.

Brushing up on his English skills was the spark that won Perrucci a scholarship to Denmark. That semester blossomed into a six-year stay, multiple degrees, his first international job opportunity, and a career with well-known global brands.

Whether it was getting onto a top MBA program or that first role at a big international company, for all the leaders we spoke to, English has proved to be a career catalyst.

More diversity, more innovation, more revenue

For companies looking to innovate and stand out in a competitive global market, an international team is essential.

“We’re aiming to build models of childcare that don’t exist at the moment”, explains Founder and CEO, .

“To do that, we need diversity of thought. With an international team, it’s more likely that someone will say “hey, I was living in Cape Verde for a while, and I saw this interesting thing”.

It’s an approach that pays off. found that businesses with more diverse management teams are more innovative, leading to 19% higher revenues.

Global customers, global team

A more diverse team can also help businesses stay close to their customers.

As technology has made it easier to operate across multiple countries, businesses quickly find themselves responding to the different needs, preferences, and expectations of customers all over the world.

“Reflecting the global nature of our business in our workforce means we can build a better, more effective service and a more successful business as a result”, explains , CEO of .

To help them stay close to their 5.2 million members across 420 cities, Zeeck’s team at InterNations is made up of more than 50 different nationalities.

English is the main language both for the InterNations team and platform, helping them create “a sense of oneness and community by using a shared language”.

The ultimate brain training

The leaders we interviewed spoke, on average, four languages, with many working across multiple languages on a day-to-day basis.

That experience of jumping between different languages also develops important leadership skills.

“When you speak multiple languages,” explains Perrucci, “different parts of the brain have to work together and make connections… It teaches your brain to be flexible about what you see and the way you interpret it”.

Zeeck likened it to working out: “Just as going to the gym improves your physical wellbeing, the mental challenge of learning a new language is good exercise for the brain”. It’s one of the reasons he provides all of his team language training.

The mental load of language

But hopping between languages and navigating different cultural nuances can take its toll.

“People whose first language is English often overlook the computing power it takes to work in your second or third language,” explains, Managing Director of International Wellbeing,, who only spends around a third of his time speaking his mother tongue.

“Even when colleagues are fluent in the language you're communicating in, it might still take them a bit more energy than you expect”, he continues. “By Friday afternoon, for example, I’m struggling to think fluently in whichever language!”.

The challenge of speaking up

For those who are less confident in their English skills, it can significantly impact the way they contribute at work.

Less than half (48%)of ESL speakers feel comfortable speaking up at work, andonly 10%of employees with limited English proficiency felt they could express themselves fully at work.

The dynamic can change depending on who’s in the room. “I see the difference when ESL speakers are on calls with confident, fluent English speakers”, adds, CEO and Founder of.

“They speak less”, she continues, “they caveat their contributions with “I might be wrong”, and you can see their English actually worsens because they feel more stressed”.

Without the right culture and support, businesses miss out on the benefits of an international team they’ve recruited.

Conscious leadership

The task of building a team and helping overcome the challenges of global working falls to business leaders.

The five leaders we spoke to shared practical tips for supporting global teams, including acknowledging and proactively addressing differences, avoiding interrupting ESL speakers, and using voice notes for sensitive communication to allow tone and emotion to come through.

More fundamentally, ESL speakers need business leaders to build a culture where it’s ok to make mistakes.

Leaders with first-hand experience of being an ESL speaker are uniquely placed to understand their increasingly global teams, pre-empt their challenges, and nurture a culture that allows difference to shine.

The journey from local roles to global leadership positions hinges on strong communication skills. The stories shared by our leaders demonstrate how English proficiency not only unlocks individual career potential but also drives organizational success through innovation and diverse perspectives. By fostering a culture that values and supports language learning, businesses can harness these benefits, ensuring their teams are prepared to excel on the global stage.

    How do English phrases travel across countries?

    By David Crystal

    All living languages change. It’s a fact of life that some people find uncomfortable, but that no one can prevent. The only languages that don’t change are dead ones.

    How does change happen? The chief way is through mutual influence, when languages – which means people – come into contact with each other. An immediate effect is that words and phrases begin to be exchanged.

    Origins of English

    The history of English shows this taking place from the very beginning. When the Germanic tribes first arrived in Britain, bringing with them the dialects that would become English, their vocabulary already contained words and phrases borrowed from Latin, a consequence of the interaction with the soldiers of the Roman Empire.

    Today we think of such words as 'butter', 'cup', 'kitchen', 'mile', and 'street' as true English words, but they are all Latin in origin ('butyrum', 'cuppa', 'coquina', 'mille', 'strata'), taken into Germanic while the tribes were still on the European mainland.

    The process continued over the centuries. An everyday word like 'take' reminds us of the Viking invasions, for this came from Old Norse 'tacan'. So did 'knife' (from 'knifr'). Even basic grammatical items were affected: 'they', 'them', and 'their' are all from Old Norse.

    When the French arrived, in the eleventh century, the borrowing became a flood, with thousands of French words expanding the vocabulary to an unprecedented size, in such domains as law, religion, politics, food, and the arts – 'duke', 'abbot', 'war', 'peace', 'pork' and 'beauty'. During the Renaissance, Latin added tens of thousands more.

    In all cases, the words traveled because cultural contact – in its broadest sense – made them do so.

    The history of contact

    This history of contact is one of the reasons that English has so many near-synonyms: we can 'ask' (from Old English), 'question' (from French), and 'interrogate' (from Latin). We can talk about a 'fire', 'flame', and 'conflagration'; 'kingly', 'royal', and 'regal'. But although French and Latin are the dominant voices, they are put in the shade by the accumulated impact of the many languages that English has since encountered as its speakers moved around the globe, especially in the days of the British Empire.

    Today, a search through the files of any major dictionary shows the presence of hundreds of languages, from 'aardvark' (Afrikaans) to 'zygote' (Greek).

    It’s been estimated that around 80 percent of present-day English vocabulary comes from languages other than the original Anglo-Saxon Germanic. English seems to always be a vacuum cleaner of a language, sucking in words from whichever culture it was in contact with. The process continues. In recent years, dictionary writers have been considering such new borrowings of words from other languages.

    But not everything in language change is due to borrowing. When we look at recent lists of updates in the dictionary world, we find hundreds of phrasal expressions, such as 'solar farm', 'travel card', 'skill set', 'cold caller', 'air punch', and 'set menu'.

    Blends of existing words form an increasingly large component of modern vocabulary, such as 'glamping' (glamorous + camping) and 'Pokemon' (pocket + monster), as do internet abbreviations, such as 'GTG' (got to go) and 'BRB' (be right back).

    And it’s here that we see the most noticeable phenomenon of the last few decades: the impact of English on other languages. The traveling is now going in both directions.

    Over a decade ago, Manfred Görlach published his Dictionary of European Anglicisms, showing English to be "the world’s biggest lexical exporter”. The book lists hundreds of words and phrases that have entered the languages of Europe. A small selection from letter 'A' shows 'ace' (from tennis), 'aerobics', 'aftershave', and 'aqualung', as well as phrases such as 'acid house' and 'air bag'.

    The factors are exactly the same as those that brought foreign words into English in the first place, such as business, culture, medicine, sport, the arts, popular music, science and technology. The difference is that these expressions come from all over the English-speaking world, with American English the primary supplier, thanks chiefly to its presence in the media.

    The impact of media

    It is the media that provides the main answer to the question “How?”. In the old days, face-to-face contact caused expressions to be shared, and it would take time for words to travel – a generation before a word would become widely used. Today, the use of English in film, television, and especially the internet allows 'word travel' to take place at a faster rate than ever before.

    A new word or phrase invented today can be around the globe by tomorrow, and if it appeals it will spread on social media and become part of daily use in no time at all. Even an everyday phrase can receive a new lease of life in this way.

    Many countries try to resist the borrowing process, thinking that an uncontrolled influx of English expressions will destroy their language.

    The evidence from the history of English shows that this does not happen. Because of its global spread, English has borrowed more words than any other language – and has this caused its destruction? On the contrary, in terms of numbers of users, English is the most successful language the world has ever seen.

    Borrowing does change the character of a language, and this too is something that causes concern. But again, I ask: is this inevitably a bad thing? Shakespeare would have been unable to write his characters in such an effective way without all those borrowings from French and Latin.

    Much of his linguistic playfulness and creativity relies on how everyday words are contrasted with their scholarly or aristocratic counterparts. In Love’s Labour’s Lost, Don Armado gives Costard a coin as a tip, calling it a "remuneration".

    Costard has no idea what the word means, but when he looks at his coin he realizes he’s been given a tiny amount. “Oh, that’s the Latin word for three farthings”, he reflects. “I will never buy and sell out of this word”. It always gets a laugh from an audience.

    Today's challenges

    Keeping up-to-date with language change is probably the greatest challenge facing foreign language learners because there is so much of it.

    Textbooks and teachers face a daily risk of falling behind the times. But the risk can be reduced if we build an awareness of change into the way we present a language. And understanding the natural processes that underlie linguistic change is the essential first step.
