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.

    Three ways to learn new English words

    By Vaughan Jones

    It’s more important for teachers to help students find ways to practice their English outside the classroom. The more efficient students become at autonomous learning, the better they’ll be able to overcome interruptions and make up for lost time.

    It will be even more challenging if you're a self-learner as you do not have a teacher looking over you and steering your learning. But it’s helpful to learn from the teaching world and pick up teacher tips that you can apply to your own studies and techniques.

    Why are learning new words so challenging?

    Students learning new words in English generally progress steadily up until the pre-intermediate and intermediate levels. But after that, they start to struggle.

    This is because there’s a big difference between the volume of the vocabulary that intermediate students and upper-intermediate students need to know.

    • Intermediate (B1/B2 level) students need to know about 2,500 words
    • upper-intermediate (B2/C1 level) students need to know about 7,500-9,000 words.

    That’s a big jump in numbers. But the real challenge is that those 5,000+ new words are not very frequent. Consequently, students don’t encounter them very often, making it difficult to recall them and leap from one level to the next.

    While there’s no simple answer to this problem, there are ways to help students overcome it. The following framework can be a big help in any classroom:

    1. Focus on the most important words:Always teach appropriate words for the levels your students are currently at.
    2. Provide memorable first encounters:You never get a second chance to make a first impression. So, ensure your student's first encounter with a new word is as memorable as possible.
    3. Teach effective word-learning strategies:Provide your students with valuable tools, tactics and resources so that they can learn new words outside the classroom, too.
    4. Organize repeat encounters:Vocabulary works on a “use it or lose it” basis, so ensure your students encounter the vocabulary you want them to learn repeatedly.

    How to teach effective word-learning strategies

    There are three steps to teach students how to learn new words effectively:

    1. Help learners maximize their exposure to English and find opportunities to use English outside the classroom

    Thanks to the internet and technology, there are many ways that students can engage with the English language outside the classroom.

    However, simple exposure to a new language is not enough – it takes much longer and is less effective than active learning. When students do something with the language they’re exposed to; it is far more memorable.

    That’s why it’s crucial for teachers to help their students seek out English in their own time and use the language, turning passive exposure into active learning.

    • Encourage students to read, listen and view things that they’re interested in or passionate about in English. For example, introduce them to new blogs, podcasts, YouTube videos, or TV series that fit their interests – since personalization leads to more effective learning.
    • Help students find ways to use English in different ways. For example, they can start a learning diary, make to-do lists in English, write social media posts, and create word cards to practice their writing. For speaking, they can record voice memos or video stories, take part in Zoom discussions, or participate in speaking projects and live classes.

    2. Provide ways for students to discover the meaning of new words

    It’s crucial to help students improve their guesswork. Instead of asking online translators to translate every time they encounter a new word, they should be able to guess the meaning of new vocabulary differently.

    • One approach is to look at the morphology of words and consider word families. For example, you can ask your students to brainstorm words with a common root. Or, you can have them identify and practice common suffixes.
    • Explore “true friends” or words that are similar in English and your student's native language.
    • Help your students figure out how to guess the meaning of a word from the context. To do this, you must ensure that your students don’t just hear or read new words but also put them into use.

    One way to get students to learn and retain vocabulary is to get them to create word cards:

    • Ask students to collect ten new words that they’re exposed to throughout the week and bring them to class, like a “show and tell” for words.
    • Then have a debate about how useful each of those words is.

    This helps to connect learning inside and outside the classroom, and it’s fun!

    3. Provide students with strategies to consolidate their knowledge of new words

    Finally, teachers should give students ideas on how to memorize words outside the classroom. You can have your students produce word cards and use a Word Store booklet to practice tasks like matching words with images or definitions.

    Lastly, it’s important to teach students memory tricks or mnemonics so they can retain the new words they encounter.
