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.

    9 English conversation mistakes to avoid

    By Mohamed Shaik

    As humans, we learn and grow through our interactions with other people. Often these encounters are centered around great conversations – rich, meaningful exchanges among a small group of people where each person actively listens and shares. Great discussions are invaluable – they enrich our understanding of people and the world around us. Socially, being someone who can engage effortlessly with others allows us to create deep friendships and gain incredible personal growth and satisfaction. In our careers, we are more effective when we work well with others – the ability to collaborate and solve problems together makes us more effective professionals and makes our businesses more successful.

    Common English conversation mistakes

    But what if you must hold a conversation in English and it is not your native language? One of the many obstacles to learning something new, like English conversation, is that it can be difficult, time-consuming and even a little scary! That’s why we put together a list of nine English conversation mistakes to avoid that apply whether you are speaking with one or several people at once. Keep these tips in mind to help you improve your interactions with people all over the world…

    1) Faking interest in the person

    One of the things that separates a conversation from a 'transaction' (such as ordering something in a restaurant) is the genuine mutual interest of each person in the other. If one isn’t interested in knowing more about the other person, neither will engage meaningfully, and the interaction will become transactional or just 'small talk'. Most people are fascinating – take the time to learn what you can about them.

    2) Discussing negative and sensitive topics

    People are more engaged and willing to share when they are relaxed and happy. Especially when you don’t know someone well, it is always better to focus on the positives – avoid both sharing your biggest troubles and bringing up topics that could be negative from a cultural, religious, political, or even personal perspective. There is always something positive to share!

    3) Trying to 'win' an argument

    Particularly when speaking with someone you don’t know well and/or someone from another country or background, it is precarious for a conversation (especially one where you are practicing your English conversation skills) to evolve into a debate or argument. It is likely that for any two people, there will be many points of disagreement, and if such differences emerge, it’s better to attempt to understand the other person’s point of view rather than to 'win' an argument. It is perfectly acceptable to agree to disagree about specific issues and move on.

    4) Disrespecting others beliefs

    If you want a great conversation, others must feel you aren’t judgmental. When someone feels their ideas and beliefs are questioned or belittled, any meaningful exchange will often shut down. Instead, try listening for understanding, and you may learn something!

    5) 'Hogging' the stage

    It is said that great actors make their fellow performers look great. It is the essence of teamwork, and the same principle applies to great conversationalists. Ask questions that allow others to be positive, confident, and maybe even a little boastful, but certainly remember to do it in a genuine way. The positive energy will be contagious!

    6) Fearing learning something unknown

    There are over seven billion people worldwide, and none are exactly like you! The greatest learning experiences are often from interactions with those who are very different from ourselves. Embrace and celebrate those differences. Allow others to share their unique perspective and journey, always keeping in mind we all share so much in common. We all want to be happy, love others, and have meaning in our lives.

    7) Trying to be someone you are not

    There’s only one person you can be, so don’t try to be someone else or something you are not. A great conversation is based on authenticity; most people can easily sense when another is not truthful or authentic. While keeping in mind all of the other rules, it’s both acceptable and expected for you to share your own journey!

    8) Monopolizing the conversation

    We’ve all been in those conversations where the other person dominates by talking incessantly. At some point, we shut down, just waiting for it to end. Active listening and learning ceases. Engagement requires participation from both parties – don’t hold back from sharing, but at the same time, don’t be that person who dominates and effectively shuts down that engagement.

    9) Focusing on superficial topics

    What separates a great conversation from 'small talk' is the meaningful nature of the dialog. Talking about the weather doesn’t elicit much other than maybe politeness. A great conversationalist elicits meaningful thoughts from others, and those come from purposeful questions. People love to think; asking them something that requires thoughtfulness deepens the conversation's value and strengthens the relationship between the parties.

    How English can help make a successful business

    By Mohamed Shaik

    In today's commercial world, proficiency in English can significantly set a successful business apart from those challenged by communication barriers. English acts as a bridge to international markets, enabling businesses to establish worldwide partnerships and connect with a broader audience.

    Effective use of English can amplify marketing strategies, enhance customer engagement, and simplify and manage the complexities of legal and financial dealings across different countries. Let's explore an example where English proficiency has been instrumental in a business's success.

    Max Kortrakul, the dynamic CEO and co-founder of the company , has become a pivotal figure in the business world spearheading innovation within Thailand's thriving stock investment scene. His mobile application, a beacon for stock investors in the region, encapsulates the surge of technology start-ups that Southeast Asia is witnessing. With the prestigious under its belt in 2014, StockRadars exemplifies the caliber of start-ups emerging from this vibrant corner of the world.

    In 2015, Southeast Asia's tech industry saw an unprecedented influx of deals, and as projected by a fascinating, the internet economy is poised to soar, potentially amassing a staggering US$200 billion annually over the course of the next decade. Amidst this digital gold rush, Max unearths his entrepreneurial saga – from seducing investors with a mere concept, to architecting a budding enterprise with English as a critical cog in reaching an impressive valuation of US$15 million.

    The genesis of a pioneering app for stock investors

    Eager to democratize the daunting task and practice of stock investing, Max identified a crucial void in the market – intuitive and user-friendly analytical tools. "Investment should be accessible. My vision was to demystify the stock market terrain for both myself and the wider audience in Thailand" he reflects. StockRadars embodies this ethos, distilling complex market data into streamlined, actionable insights, accessible right from your smartphone.

    From sleepless nights to a sound business proposition

    Max was burning the midnight oil when inspiration struck - that unshakable idea that jolts you awake at 3 a.m. Consumed by potential, he channelled all his energy and focus into writing and crafting the app. "It's about conviction and the audacity to give life to your concept," Max states. "Some ideas propel you into the celebrated ; others are stepping stones to the next big venture."

    The art of engaging investors

    Successful fundraising transcends mere numbers. For Max, it hinged on substantiating his commitment and the sweat equity he poured into StockRadars. "Investors bet on people, not just ideas" he states. Presenting the app as a tool that could help alleviate risk and simplify stock market investment was key to unlocking investor confidence.

    Tackling pitchroom anxieties

    "I shunned the notion of insignificance," Max admits. Being from a region sparse in tech success stories, he focused on his personal goals and conviction to succeed rather than his country’s size.

    Navigating the pitch in English could intimidate, but Max was a proponent of simplicity over jargon. His prior stint in an IT firm in Vietnam had polished his own English skills and vocabulary, a skill he used to his advantage.

    Multicultural mindsets driving innovation

    Working in diverse environments has broadened Max's horizons, teaching him the value of "English variants" in seamless communication. "Diversity shapes our business ideology" notes Max. Interns from Nepal and England have enriched StockRadars, bringing distinct perspectives to the table and fuelling innovation.

    The language of opportunity

    "English is the connective tissue in the global business landscape" Max asserts, underscoring its significance in multiplying prospects and fostering networks. With Southeast Asia becoming a fertile ground for tech start-ups, English proficiency is not just an asset; it's a gateway to turning start-up visions into tangible successes.

    Why is English so important in business?

    In today's global economy, where over 1.5 billion people speak English, it serves as a crucial tool enabling cross-border collaborations and partnerships.

    For successful entrepreneurs, like Max, proficiency in English is not merely an academic accomplishment but a strategic business tool that enables effective communication across diverse cultures and geographic boundaries. It breaks down barriers, allowing businesses to access and engage with international clients, partners and investors effortlessly.

    In settings where colleagues of diverse nationalities meet, English is the shared language that promotes effective communication and understanding, boosting workflow efficiency and fostering workplace inclusivity. Whether it's negotiating deals, drafting contracts, or conducting marketing campaigns, English proficiency is essential, enhancing professional capabilities across various sectors.

    Therefore, speaking and mastering English is not merely a skill but a critical asset, increasing occupational prospects and driving careers and business success in a world where many professionals consider it the language of global business.

    This linguistic skill enhances understanding of global market trends and consumer demands, fostering opportunities for collaboration and innovation. Furthermore, English is the predominant language of the Internet, digital marketing and global trade agreements, making it indispensable for businesses aiming to develop and capitalise on e-commerce and digital platforms.

    In essence, for many business professionals, English is more than a language; it is a catalyst for business expansion, innovation and competitive edge in the increasingly interconnected global economy.
