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.

  • A Parent reading to his two children from a book with all three of them laying on the floor

    How can teachers encourage parents to get kids reading at home?

    By Donatella Fitzgerald MBE

    “Sharing a story with your child is one of the most incredible things you can do for them.” – .

    Research shows that getting kids reading at home can increase their reading ability at school – and improve their overall well-being. Parents and guardians can make a big difference. But how can teachers encourage parents to get their children to read more at home? We explore some strategies you can use.

    Tell parents about the benefits

    Reading can give children a break from technology-centered activities. It can help them to relax and unwind; reading a book can make children laugh and feel happier! Through hearing stories, children are also exposed to a rich and broad vocabulary.

    “It is important for teachers to establish contact with parents as much as possible and give very clear guidelines on the benefits of reading, and how they can create a reading routine and help their children read at home,” says Kasia Janitz-De La Rue, Product Development Director at app.

    So, encourage parents to find time for a reading routine. Just before bedtime is a great time, as .

    Give parents practical ideas for reading strategies

    Encourage parents to read with and not to their child. It doesn’t matter how long they set aside to read – just 10 minutes of quality reading time can make a big difference.

    Here are a few tips concrete reading tips for teachers to share with parents:

    • Ask children lots of questions while reading.
    • Use encouragement and praise to keep children engaged. Saying things like “what fantastic ideas” or “you thought so carefully about that, what might happen now?"will keep their minds working.
    • Use their past experiences to talk about what’s being read. Things like “have you learnt about…at school?” or “do you remember when we watched…and found out about…?” are good conversation starters.
    • Tune in and listen to children, and be curious about their interests. “I didn’t know you knew so much about…” or “I love reading stories about…with you,” are good phrases to keep in mind.

    It’s also a great idea to share online resources with parents. You can also suggest that parents look up read-aloud YouTube videos featuring authors, teachers or librarians reading their favorite stories. This way, children can watch and listen as often as they like.

    Recommend graded readers

    Graded readers are books that use language in line with a child‘s learning level. They can help children build confidence, and help slowly expose them to authentic reading levels.

    Encourage parents to identify what genre their child is interested in and show them the readers available. Each time parents see their children move up a level, they’re sure to see their children’s love for reading grow.

    Suggest before, during, and after reading activities

    Before reading

    Parents can take turns with their children to predict what the story is about – or what will happen next. Here is an activity teachers may suggest they try:

    “Start with the cover of the book and the blurb on the back cover. Reveal the cover slowly to ask the child what they can see. Ask them to guess what is on the cover. Once they have seen the cover, ask them questions about the images on the cover – who, what, why, where and how?”

    While reading

    Remind parents to focus on their children’s reading comprehension by using strategies like prediction, questioning, clarifying, and summarising. Teachers can ask parents to:

    • check ideas and understanding as the child reads: ‘So, you think that….’ ‘Did you expect…to happen?’ ‘Why do you think that happened?’
    • use the pictures in the book to help with comprehension
    • describe what is happening and talk about the characters.

    After reading

    Don’t forget: parents can continue to explore the book’s topic once reading time is done! A few ideas to share with parents include:

    • organising a puppet show for family members and siblings after making puppets of the characters in the book
    • having children draw a picture of their favorite character or their favorite page in the story
    • encouraging children to express their opinion on the book.
