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.

    5 ways to improve English test results

    By Charles Hamilton

    As with all tests, adequate preparation is crucial. For many aspiring migrants needing to take an English test, it may have been several years since they took an official exam. Knowing how to prepare effectively and what to expect on the day are key when it comes to securing a successful outcome. Use these five exam preparation tips below to improve your English test results.

    1. Familiarise yourself with the type of test questions you will be asked and know what to expect on the day

    The official guides published by the testing bodies are an excellent source of information to help you fast-track your learning. They offer materials that replicate the real test questions as well as guidance and strategies for dealing with every task set. Taking a practice test in exam-like conditions helps to improve time management skills and set realistic expectations on your potential performance.

    As with all high-stakes tests, security arrangements at the test center are strict. Test takers need to prove their identity via a passport or similarly approved document, so it’s a good idea toarrive at least 30 minutes beforethe test time and have your documents to hand.

    2. Give yourself enough time by setting clear, measurable and achievable goals. This will help keep your motivation up and your end goal in sight

    Start with a detailed understanding of your current English proficiency. That makes it easier to focus on any weaker areas ahead of taking the test and plan how long you’ll need to study for to bring your skills up to the required level.

Many test-takers take advantage of the large amount of free preparation material that includes everything from print and digital course guides to practice tests. A huge amount of information is also posted on YouTube, including tutorials and advice covering the range of different tests on offer.

    5. Be persistent – keep practicing at every opportunity

    Make the most of those spare minutes to practice your skills. Every workday includes a little downtime so try to incorporate a few short 5 or 10 minute practice activities each day to keep building your knowledge.

    IELTS has long been the standardized test approved by the Australian government and the test of choice for visa applicants both for work and study. Since November 2014, in an effort to make it more convenient for applicants, the DIBP has approved a number of additional tests that can be used as proof of English language skills, including TOEFL iBT, Cambridge English Advanced (CAE) and the  (PTE Academic).
