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.

ɫèAV 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.

    7 ways to individualize your teaching

    By Andrew Walkley
    Reading time: 4 minutes

    There's no denying that tailoring your teaching to individual students is an effective strategy. However, many teachers struggle with finding the time to include teaching moments which address an individual learner's specific needs. So, what's the best way to create an individualized classroom? Andrew Walkley, co-author of Roadmap, explains the benefits of this approach and shares some techniques to ensure that every student gets the most out of your lessons.

    The best of both worlds?

    First of all, what does individualized teaching mean? It's the concept that students will learn most effectively when the activity is specific to their needs and the language they are using is appropriate for their level. This concept is sometimes seen in opposition to coursebooks and class-based learning, where students are all expected to follow the same syllabus. However, class syllabuses and coursebooks have the following benefits:

    • Providing students with common goals
    • Encouraging learners to follow an unfamiliar topic that then opens new doors of learning
    • The learning opportunities in peer-to-peer explanation

    When we talk about individualized teaching in the classroom, we want to exploit the benefits of learning together while also providing opportunities for more individualized development. So, how can you, as a teacher, combine the two approaches?

    1. Involve students in choosing your route

    All classroom groups are different and made up of people from different age groups with distinct needs and interests. Roadmap can help in two ways:

    1. There is a fast and slow track. The fast track focuses on language input and speaking. The slow track has additional skills lessons at the back of the book that are thematically linked to the corresponding fast track lesson.
    2. Each lesson has a clear goal and final task. For shorter courses, get each student to choose three tasks they would definitely like to do. Based on the results, you can prioritize those lessons.

    At the start of the course, make a point of asking about students' learning priorities and then plan accordingly. Once you've completed an input and speaking lesson, you can ask the students if they want to further explore the topic through the skills lesson.

    2. Make use of tasks

    Open tasks, where students exchange their own ideas in a meaningful way, are a key part of individualized lessons. In essence, they are self-differentiating because each student will attempt to complete the task using whatever language they are able to use. In Roadmap, each of the main lessons ends with a clear task connected to a Global Scale of English (GSE) can-do statement. However, there are also lots of other speaking opportunities without a 'speaking' label (under vocabulary or reading, etc.), as well as the conversation that typically occurs in any lesson, all of which can be treated as open tasks.

    3. Give individualized feedback and then share it

    In a group setting, it's impossible to give individual feedback on every single task. However, you can give individual attention to different people throughout the lesson. Make yourself available to give students the language they need as it arises during an activity. Then, when they've completed the task, write some of these examples on the board, but leave a gap for the keywords. Elicit these keywords from other members of the class. If they can't get it, ask the student(s) you helped to explain the missing language. You might then repeat the task, but this time, pay attention to a new group.

    4. Check what vocabulary students know

    All coursebook writers and teachers make choices about what vocabulary to introduce to students. In the case of Roadmap we are guided by the GSE and teachers might like to experiment themselves using the GSE Teacher Toolkit. However, all students will have their own lexicons. You can individualize learning better by asking students to rate the words you aim to cover in a unit according to whether they know them or not. For example, 1 = it's completely new, 2 = the meaning is familiar but I don't use it, 3 = this is part of my productive vocabulary.

    5. Get students to create their own word lists and cards

    This knowledge will enable you to encourage students to focus on their individual vocabulary needs. They can reinforce learning by developing a word list or making flashcards using a web tool such as Quizlet. For new words they may have a word/collocation with an L1 translation.

    With familiar vocabulary, they could have cards with a keyword on one side and varied collocations or common examples on the other (also in English). It's worth setting aside some time in class to do this at the start of a course. If your students are engaged and motivated, it can become a regular discipline for learning new vocabulary.

    6. Ask more open questions about usage, not just meaning

    When we do vocabulary tasks from the course material in class, we can use open questions to individualize learning with the following two techniques. Firstly, as you go through the answers, rather than going in order 1 to 8, you can nominate people to give the answer that they're most unsure of and want to check. Secondly, we can ask the rest of the class open questions which focus on how words are used. For example, take these questions from different vocabulary exercises in Roadmap B1+:

    • What (other) things might you spill?
    • Why might a character in a series be killed off?
    • What (else) can you describe as reliable?
    • What can someone do to stay calm?

    You could also ask questions such as, "What's the opposite of staying calm?" or "What might you say if you spilled something?"

    When you ask these questions, you are checking meaning, but more importantly, you are also pushing students to reveal how well they know a word. Do they know the collocations of spill and reliable? Do they have the other language they might need to talk about the aspects of a TV series or help someone who is in a panic? You can then encourage students to choose how much of this potentially new language they want to add to their word lists.

    7. Provide open homework tasks and make time to share the results

    Homework is another opportunity to individualize learning. Give students a wide choice of tasks based on the material of the course or beyond, for example:

    • Choose any number of exercises they want to do from workbook material
    • Find and read one article they are interested in (in L1 or L2)
    • Write five things they want to learn how to say in English (perhaps using Google Translate)
    • Write up an interesting conversation they had in English (the conversation could be originally in L1 or L2)

    Whatever task they choose, the key is to dedicate some classroom time to discussing which homework task they did and why. Encourage them to explain their answers and what they learned through the task, and whether or not they would choose to do a similar task again.
