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.

    The beginning days of school are both exciting and occasionally nerve-wracking for teachers and students alike. Everyone is adjusting to new faces, routines and a fresh environment. As a teacher, you can help make this shift smooth, inviting and enjoyable. One effective way to achieve this is by using icebreaker activities.

    Icebreakers are simple games or activities that help students get to know each other, feel comfortable and start building a positive classroom community. When students feel connected, they are more likely to participate, help each other and enjoy learning. Here are some easy-to-use icebreaker activities and tips for making the beginning of the school year memorable for everyone. Here are just a few ideas for icebreakers you can use in your classroom.

    How AI and the GSE are powering personalized learning at scale

    By
    Reading time: 4 minutes

    In academic ops, we’re always finding the balance between precision and practicality. On one side: the goal of delivering lessons that are level-appropriate, relevant and tied to real learner needs. On the other hand, we juggle hundreds of courses, support teachers, handle last-minute changes and somehow keep the whole system moving without losing momentum or our minds.

    That’s exactly where AI and the Global Scale of English (GSE) have changed the game for us at Bridge. Over the past year, we’ve been using AI tools to streamline lesson creation, speed up course design and personalize instruction in a way that’s scalable and pedagogically sound.

    Spoiler alert: it’s working.

    The challenge: Customization at scale

    Our corporate English learners aren’t just “students”. They’re busy professionals: engineers, sales leads, analysts. They need immediate impact. They have specific goals, high expectations and very little patience for anything that feels generic.

    Behind the scenes, my team is constantly:

    • Adapting content to real company contexts
    • Mapping GSE descriptors to measurable outcomes
    • Designing lessons that are easy for teachers to deliver
    • Keeping quality high across dozens of industries and levels

    The solution: Building personalized courses at scale

    To address this challenge, we developed an internal curriculum engine that blends the GSE, AI and practical, job-focused communication goals into a system that can generate full courses in minutes.

    It is built around 21 workplace categories, including Conflict Resolution, Business Travel and Public Speaking. Each category has five lessons mapped to CEFR levels and GSE descriptors, sequenced to support real skill development.

    Then the fun part: content creation. Using GPT-based AI agents trained on GSE Professional objectives, we feed in a few parameters like:

    • Category: Negotiation
    • Lesson: Staying Professional Under Pressure
    • Skills: Speaking (GSE 43, 44), Reading (GSE 43, 45)

    In return, we get:

    • A teacher plan with clear prompts, instructions and model responses
    • Student slides or worksheets with interactive, GSE-aligned tasks
    • Learning outcomes tied directly to the descriptors

    Everything is structured, leveled and ready to go.

    One Example: “Staying Organized at Work”

    This A2 lesson falls under our Time Management module and hits descriptors like:

    • Reading 30: Can ask for repetition and clarification using basic fixed expressions
    • Speaking 33: Can describe basic activities or events happening at the time of speaking

    Students work with schedules, checklists and workplace vocabulary. They build confidence by using simple but useful language in simulated tasks. Teachers are fully supported with ready-made discussion questions and roleplay prompts.

    Whether we’re prepping for a quick demo or building a full 20-hour course, the outcome is the same. We deliver scalable, teacher-friendly, learner-relevant lessons that actually get used.

    Beyond the framework: AI-generated courses for individual learner profiles

    While our internal curriculum engine helps us scale structured, GSE-aligned lessons across common workplace themes, we also use AI for one-on-one personalization. This second system builds fully custom courses based on an individual’s goals, role, and communication challenges.

    One of our clients, a global mining company, needed a course for a production engineer in field ops. His English level was around B1 (GSE 43 to 50). He didn’t need grammar. He needed to get better at safety briefings, reports and meetings. Fast.

    He filled out a detailed needs analysis, and I fed the data into our first AI agent. It created a personalized GSE-aligned syllabus based on his job, challenges and goals. That syllabus was passed to a second agent, preloaded with the full GSE Professional framework, which then generated 20 complete lessons.

    The course looked like this:

    • Module 1: Reporting project updates
    • Module 2: Supply chain and logistics vocabulary
    • Module 3: Interpreting internal communications
    • Module 4: Coordination and problem-solving scenarios
    • Module 5: Safety presentation with feedback rubric

    From start to finish, the course took under an hour to build. It was tailored to his actual workday. His teacher later reported that his communication had become noticeably clearer and more confident.

    This was not a one-off. We have now repeated this flow for dozens of learners in different industries, each time mapping everything back to GSE ranges and skill targets.

    Why it works: AI + GSE = The right kind of structure

    AI helps us move fast. But the GSE gives us the structure to stay aligned.

    Without it, we’re just generating content. With it, we’re creating instruction that is:

    • Measurable and appropriate for the learner’s level
    • Easy for teachers to deliver
    • Consistent and scalable across programs

    The GSE gives us a shared language for goals, outcomes and progress. That is what keeps it pedagogically sound.

    Final thought

    A year ago, I wouldn’t have believed we could design a 20-lesson course in under an hour that actually delivers results. But now it’s just part of the workflow.

    AI doesn’t replace teaching. It enhances it. And when paired with the GSE, it gives us a way to meet learner needs with speed, clarity, and purpose. It’s not just an upgrade. It’s what’s next.

    Back to school: Inclusive strategies to welcome and support students from day one

    By
    Reading time: 3 minutes

    As the new school year begins, teachers have an opportunity to set the tone for inclusion, belonging and respect. With the right strategies and activities, you can ensure every student feels seen, heard and valued from the very first day. Embracing diversity isn’t just morally essential: it’s a proven pathway to deeper learning, greater engagement and a more equitable society (Gay, 2018).

    Research consistently shows that inclusive classrooms foster higher academic achievement, improved social skills and increased self-esteem for all students (Banks, 2015). When students feel safe and respected, they are more likely to take risks, collaborate and reach their full potential.
