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 English conversation works

    By Richard Cleeve

    English language teachers everywhere spend time and energy helping students practice their conversation skills. Some may ask whether conversation in English can actually be taught. And – if it can – what the rules might be.

    To explore these questions, we spoke to world-renowned . He is an Honorary Professor of Linguistics at the University of Bangor and has written more than 120 books on the subject.

    What makes a good conversation?

    “It’s very important that we put this everyday use of language under the microscope,” he says. He highlights three critical facets of conservation that we should bring into focus:

    • Fluency
    • Intelligibility
    • Appropriateness

    But all in all, he says that people should walk away from a conversation feeling like they’ve had a good chat.

    “For the most part, people want that kind of mutual respect, mutual opportunity, and have some sort of shared topic about which they feel comfortable – and these are the basics I think.”

    The rules of conversation

    There are plenty of ways you can teach learners to engage in a successful conversation – including how to speak informally, use intonation, and provide feedback. So let’s take a look at some of the key areas to focus on:

    1) Appropriateness

    Fluency and intelligibility are commonly covered in English language classes. But appropriateness can be more complicated to teach. When preparing to teach conversational appropriateness, we can look at it through two different lenses: subject matter and style:

    2) Subject matter

    “What subject matter is appropriate to use to get a conversation off the ground? There are cultural differences here,” he says. The weather is often a good icebreaker, since everyone is affected by it. The key is to find a common topic that all participants can understand and engage with.

    3) Style

    Teachers can also teach students about conversational style, focusing on how to make conversations more relaxed in English.

    There are “several areas of vocabulary and grammar – and pronunciation too, intonation for example – as well as body language, in which the informality of a conversation is expressed through quite traditional means,” says David. One example he offers is teaching students how to use contracted verb forms.

    4) Simultaneous feedback

    This is what makes a conversation tick. When we talk with someone, we let them know we’re listening by giving them feedback. We say things like “really” or “huh” and use body language like facial expressions and gestures.

    Of course, these feedback noises and expressions can be taught. But they won’t necessarily be new to students. English learners do the same when speaking their own language, anyway.

    Keep in mind though, that when it comes to speaking online on video conferencing platforms, it’s not easy to give this type of simultaneous feedback. People’s microphones might be on mute or there might be a delay, which makes reacting in conversations awkward. So, says David, this means online conversations become much more like monologues.

    5) Uptalk and accents

    Uptalk is when a person declares something in a sentence, but raises their intonation at the end. For English learners, it might sound like someone is asking a question.

    Here’s an example:

    • “I live in Holyhead” said in a flat tone – this is a statement.
    • “I live in Holyhead” said using uptalk – you are stating you live here, but recognize that someone else might not know where it is.

    Now, should teachers teach uptalk? David says yes. For one, it’s fashionable to speak this way – and it can be confusing for English learners if they don’t understand why it’s being used in a conversation.

    “The other thing is that we are dealing here with a genuine change in the language. One of the biggest problems for all language teachers is to keep up to date with language changes. And language change can be very fast and is at the moment,” he says.

    When it comes to accents, David is a fan. “It’s like being in a garden of flowers. Enjoy all the linguistic flowers,” he says, “That’s the beauty of language, its diversity”.
