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.

    Acing the ɫèAV English International Certificate: 10 essential revision strategies

    By Amy Malloy

    Every student and teacher knows how important revision is ahead of exams. It’s not only about how much students revise and practice – it’s also about how they do it.

    So, if you or your students are preparing for the ɫèAV English International Certificate (PEIC), here are ten top revision strategies to help. All of the advice below can be applied to all six levels from A1 to Level 5.

    Know what to expect

    You can download detailed 'Functions and Notions' guides for all levels. These will give you a very clear idea of the language we expect students to produce at each level. You can download the test guides for each level as well as practice tests and other important documents.

    Work on synonyms and paraphrasing

    Often in the reading and listening tasks, the answers will be synonyms or paraphrased versions of the question. Working with synonyms and paraphrasing in class or at home is a great way to expand vocabulary and help be better prepared for the test. In the A1 test students are expected to show only “a very basic repertoire of words and simple phrases”, but as they progress through the levels, more range is expected in vocabulary and grammar.

    Focus on sentence structure

    As well as helping to improve grammatical control, taking a close look at sentence structure will really benefit you or your learners, especially in the dictation task (section 2). Identifying the tense of a verb or whether they need to use this or these, for example, will help you avoid losing points unnecessarily. It’s also important that they check sentences are complete and correct in the gap-fill tasks at higher levels (Sections 3 and 7), so always tell them/make sure to re-read the whole sentence for every question.

    Create a list of errors

    We all know that learners often make the same mistakes, so a good idea is for them to create a personalized errors list.

    Teacher: Each time you do a writing task, dictation, or gap fill, have them write down the typical mistakes they make. Then, next time, tell them to check their work with their list before you correct it.

    Self-learner: Make sure to take note of the mistakes you make and put them into a list, taking care to avoid them in the future.

    Use a highlighter

    Get yourself or your students into the habit of highlighting or underlining keywords in questions every time you do a task. This helps learners focus on the information they need to listen or look for and also encourages them to subconsciously start thinking about vocabulary related to the topic. This could be practiced by downloading a sample exam and practicing underlining the keywords.

    Say more

    For the spoken test, train your students to expand their answers and make sure they feel comfortable talking about themselves. At higher levels, give your learners language so they can support their point of view. Remind them that the topics may be more complex, but they still need to be able to give an opinion about them.

    Listen to as much as possible

    In the listening sections, learners will hear a variety of different accents from people of different ages, so it’s important to expose them/yourself to lots of different voices in preparation for the test. That might be a parent talking to a child or an elderly person in a shop, so the more experience someone has listening to different dialogues, the better. As well as the listening activities in coursebooks, encourage students to listen to podcasts or watch videos on YouTube in their free time.

    Be (in)formal

    In the writing and role play, it’s important for learners to know what level of formality is required for each task. They should have lots of practice in written and spoken structures to deal with different types of people, such as a friend, a shop assistant or a bank manager. Also remind them to make the most of the 15 seconds they have to prepare the role play in the spoken test and think about the type of structures and vocabulary they’ll need.

    Keep to the word limit

    For each of the writing tasks, there is a ‘tolerated word limit’ which allows students to be a few words over or under. However, you should train learners to keep an eye on how much they are writing so they become familiar with the required task length. Students can save time calculating exactly how many words they’ve written by choosing an average line from their writing, counting the number of words on that line and then multiplying it by the total number of full lines.

    It’s also essential students practice writing under exam conditions so they get used to completing the tasks quickly. Be sure to include some exam practice in class or as a self-learner, try to practice with a past exam paper in a quiet place, replicating exam conditions as closely as you can.

    Check the answers again

    While our final tip isn’t really a revision strategy, it’s certainly very helpful for students to bear in mind when applying all of the other revision strategies. It is essential that students leave themselves time at the end of the test to check through their paper: Have they filled in every question? Are the sentences complete in the gap fill tasks? Have they checked their writing and remembered their frequent mistakes? Are all the answers clear and easy to read? One final check-through could make all the difference!

    With these top tips, you or your students will be more than ready for the test. Good luck!

    Mindfulness activities for kids to reduce stress

    By Amy Malloy

    How can we help children (and ourselves) deal with turbulent situations?

    As humans, we are programmed to position ourselves according to the constants around us: people, structures and boundaries. When those constants shift, it can be unsettling for adults and children.

    Sometimes we find ourselves in unprecedented situations, and we each have our own approach to managing things. If you feel confused and without direction because of a turbulent situation, please know that that is okay.

    We’ll look today at why that is, to help us understand ourselves a little more and why these simple mindfulness activities can help us navigate it.

    What causes social stress?

    There may be many reasons for feeling stressed in life, but during turbulent times in society, it is often due to not feeling safe.

    Something in our environment is alerting our survival instinct. This makes our brains produce stress hormones, which get us ready to fight the threat, run from it, or freeze until it’s gone away.

    The threat might be to our physical or even social survival – and the two are linked. Things can feel even scarier when we also feel isolated from our social group, which keeps us protected from that threat.

    Human beings are social by nature. We live and work in communities, we connect through love and empathy and we protect each other. There’s truth to the saying“there’s safety in numbers”.

    But it’s not just about safety. We also define ourselves by comparing ourselves to others and working out what we are not.

    Research has found that we identify deeply with our role in society and the ‘pack’ to which we belong. This holds deep ties with our sense of safety, contentment and self-esteem. If the boundaries by which we define and position ourselves have shifted or continue to shift, we will feel unsafe, threatened and therefore stressed.

    Are children affected by social stress in the same way?

    If we then apply this to children, the constants to whom they look for security are the adults in their life. If the adults are behaving differently, the children will feel a shift and feel unsafe and stressed too. If they don’t have their friends alongside them for social positioning, this too can lead to them feeling confused and uncertain.

    Here are some key ways we can help:

    Communicating and listening

    Children may often lack the language to express what they are feeling, or even to recognize it themselves. Therefore, we must offer ways to help them make sense of the world around them, to help them feel safe and to help express their concerns.

    Communication provides the necessary social interaction and models for them on how to handle the new situation. It firms up their boundaries, and provides a safe space where they feel listened to and acknowledged and this, in turn, helps diffuse their stress.

    The activity below is a lovely way to invite children to express any worry they might be feeling, mindfully and with support – and give them something to do with their feelings. It also has the benefit of helping them breathe fully and slowly, which will calm down their nervous system.

    Breath activity: Worry bubbles

    1. Sit together and invite your child to put their palms together.
    2. Invite them to take a big breath in. As they breathe in, they can draw their palms further and further apart, spreading their fingers as they imagine blowing up a big bubble between their hands.
    3. Invite them to whisper a worry into the bubble.
    4. Invite them to blow the breath out nice and slowly. As they breathe out, they can imagine blowing the bubble (and the worry) away with a big sigh.
    5. Twinkle the fingers back down to the lap, and start again, either with the same worry or a new one

    Helping them find a safety anchor inside themselves

    By helping children focus on breathing, we can teach them that even if things feel wobbly around them, their breath is always there. The act of focusing on the breath also helps settle the fight or flight branch of their nervous system into a calmer, more balanced state.

    Breath Activity: Counting breaths

    1. Invite your child to sit with you.
    2. Invite them to place their hands on their tummy and breathe in slowly so they push into their hands, counting slowly up to four.
    3. As they breathe out, invite them to count up to six, as they slowly empty the belly and their hands lower back down.
    4. Continue until they feel calmer. You can do this every morning or evening to help sustain balance. With younger children, they might like a teddy on their tummy to push up and down!

    These two activities can be lovely daily practices to try and provide some safety and structure to your child or students’ mental health right now. They are also enjoyable activities to try for yourself – you may like to increase the in and out count of the breath a little bit for an adult breath.
