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.

    What is rapid prototyping and how can it apply to the ELT classroom?

    Tom Chi is an internet veteran with quite a resumé. His roles have been many and varied – from astrophysical researcher to Fortune 500 consultant and corporate executive, developing new hardware and software products and services.

    He worked on Microsoft Outlook when it was in its infancy, was a major influence in taking Yahoo Search from 0 to 90 million users and is now Head of Product Experience at Google X – Alphabet’s secretive division focused on creating technological innovations for the future. It has produced the self-driving car and Google Glass, and its Project Loon aims to provide internet to every square inch of the earth.

    At Google X, Tom was in a unique position – always having to think five, ten or even more years ahead in order to conceptualize and build the technology of the future. As you might imagine, this is far from an easy task; not only do the ideas have to be original, but they have to meet people’s future needs – something that is not easy to predict.

    So, how does Tom and the others at Google X deliver their vision for the future using today's materials and technology?

    That’s where Rapid Prototyping comes in. It’s a concept that allows teams to experiment, learn and adjust prototypes quickly and cheaply, so that projects (and products) get off the ground. Failure is seen as a starting block and an inevitable part of the learning process. Following his workshop, we are going to look further at rapid prototyping and how it can relate to the ELT classroom.

    4 career moves for enthusiastic teachers

    By Nicole Kyriacou

    Have you been teaching for a number of years and are looking for ways to challenge yourself and share your experience and passion with others?

    Many would love the opportunity to progress in their careers and try new things but have no idea how to get started.

    So, let's look at several potential jobs for English language teachers, find out what they involve and how you can improve your chances of getting a foot in the door.

    1. Materials Writing

    For those with a passion for writing and an eye for detail, ELT materials development could be for you. While writing can be hard to get into, there are several ways to get involved - especially if you are persistent and build a portfolio.

    Here are some of our top tips for aspiring materials writers:

    • Create your own materials in class and think of ways of adapting the current materials you use for different ages or levels.
    • Share the materials you make with other teachers and get them to give you feedback.
    • Review materials for a publisher. Not only will you start to think more critically, but if you do a good job they might commission you to do some writing for them. One way to discover these opportunities is by signing up for their newsletters or following them on Facebook or .
    • Start a blog and share lesson tips, advice and activities with other teachers. If it becomes popular enough someone from a publisher might spot you and invite you along for an interview.
    • Join the , where you can create an account and publishers can contact you directly if they are interested in your profile.
    • Finally, write as much as possible - and get people to read your work. Listen to their feedback and take steps to constantly improve your output. You get better and faster at it at the same time.

    2. Examining

    If you like teaching exam classes, there's a good chance you'll enjoy examining too. Training to be a speaking examiner is a great way to earn some extra money and can also help you better understand test formats and mark schemes. This will certainly also benefit your students in the future too.

    Specific requirements for examiners vary depending on the exam board. However, as a rule of thumb, you need a lot of experience teaching the level you wish to examine at. Here is an from app outlining the expertise and competencies required to be a PTE General Examiner.

    You can also check out the recruitment sites from , and to get more of an idea if you are eligible.

    Like materials writing, examining can be very competitive, so here is some advice to help you get started:

    • Teach more exam classes. The more variety and levels you do, the more opportunities you'll have.
    • Familiarize yourself with the mark schemes to give you a deeper understanding of how examiners think. Most of this information can be found in teacher handbooks like this one for .
    • Help organize mock exams at your school. This will give you valuable experience examining as well as organizing students and materials.
    • Start as an invigilator for written exams. If you do a good job, it'll show that you are competent and you'll learn more about how exam days are structured.
    • Contact your local exam center and introduce yourself. And who knows? They might even be recruiting.

    3. Academic Management

    Another common career goal for long-term English teachers is to become an Academic Manager or Director of Studies (DoS). A successful DoS assumes many roles; often having to organize teachers' schedules, deal with students' concerns, develop new courses, and find cover (or teach) classes at the last minute. They may also need to help with the school's marketing and business side, too.

    Many academic managers are employed internally, so get involved with what is going on at your school and apply for smaller coordination positions to see if it's something you enjoy.

    You can also try:

    • Offering to help with placement testing of new students. This will help you get to know the type of students at your school and the objectives they have, and also learn more about the levels and courses on offer.
    • Not limiting yourself to teaching one kind of course. If you work at an academy that offers courses for young learners, teens, adults, exam preparation, business etc., try them all. A good DoS should be able to offer advice to all the teachers.
    • Taking a course - most academic managers will be expected to have an advanced TEFL qualification like a DELTA, an MA TESOL or something similar. Specific leadership and management courses are available for those who want to specialize in this area, such as Leadership in ELT.
    • Offering creative ideas or constructive criticism to the current management team about how the school runs and what you think could be even better.
    • Organizing an event for teachers and students to show you are interested and have the type of skills that are needed.
    • Apply for academic management positions in summer schools to give you a taste of what's to come.

    4. Teacher Training

    If you are interested in teaching methodologies and sharing your knowledge with others but not keen on the admin side, then teacher training might be for you.

    As a teacher trainer, you may be required to run workshops on various topics, observe teachers and offer feedback and help with lesson planning. This means it's vital that you can listen to others carefully and clearly explain things.

    Here are some ideas to give you a better chance of finding work as a teacher trainer:

    • Organize informal workshops at your school. Encourage teachers to share ideas that have worked well for them with the rest of the staff.
    • Try team teaching where you and a colleague teach a class together. It's a great way to learn from each other and give your students a new experience.
    • Practice giving feedback by doing peer observations with other teachers.
    • Submit a proposal for a conference to see if you enjoy presenting.
    • Mentor a new teacher at your school.
    • Take an advanced teaching qualification to boost your knowledge.
    • Find teaching work in a school that also run their own initial teaching qualifications like the CELTA or Trinity CertTESOL. If you impress the DoS with your teaching skills - they may recommend you get involved with the teacher training department.

    Where to apply for jobs

    The best place to look for new opportunities is often at the school where you currently work. Start by trying new things and showing an interest in the day-to-day running of the organization. Once you've got the attention of the management it will be easier to negotiate a new position. However, if you work at a small school with fewer chances to grow professionally, think about moving to a new school.

    Other good places to look for new positions include:

    • Linkedin (don't forget to update your profile and ask for recommendations from colleagues)
    • Local teaching Facebook groups
  • A teacher leaning on a table where students are working on various activities

    6 tips for planning your first English classes

    By Nicole Kyriacou

    You are nervous, yet excited. You want to appear relaxed and fun, but still be taken seriously. Most of all, you are keen to make an excellent first impression.

    With all that in mind - planning your first English classes of the year can be a daunting experience.

    Here are six things to consider when planning your first classes:

    1. Set clear aims

    Whether you are teaching young learners, teenagers or adults, it’s important you discuss the aims and objectives of the course from day one. You’ll need to learn more about your students' needs to do this. Why are they learning English? Do they want to prepare for an official exam? What activities do they enjoy? What things do they need to improve the most?

    The way you do this will depend on the age of your learners. For example, with adults and teens, you could get them to interview each other and write a report about what they found out. With younger children, do a survey they can complete using smiley faces.

    2. Find out students’ interests

    Although you should understand your students' needs and why they want to learn English - to help make your classes relevant and engaging - you should also discover what they enjoy doing outside of class.

    To do this, get students to write mini bios you can stick around the classroom. Or have them prepare presentations where they share something they are passionate about with the rest of the class - using coursebooks. As a class, go through the contents page, vote on which topics students find most interesting, and start with those.

    3. Break the ice

    You want your first class to be fun so that students are motivated, and associate English language learning with something they can enjoy. Ice-breakers can also be an excellent way to get to know each other and learn about your students' current level of English.

    Activities where students have to ask each other questions work well.

    4. Provide a comfortable environment

    Young learners and teenagers tend to be shy at the start of a course - especially if they don’t know each other. Develop a rapport and break down boundaries by including team-building activities in your first class.Your aim is to have all the students feeling more comfortable with each other before the end of the lesson so that there are no awkward silences in future lessons.

    5. Manage expectations

    Managing expectations is an essential part of a teacher's job. Make sure in the first class you are clear about what you expect from your students and what they can expect from you.

    Have students brainstorm the rules for the class and then make a big poster or ‘class contract’ which all students have to sign. Display the poster on the wall so you can always refer to it if someone misbehaves.

    Try to keep the rules as positive as possible. Instead of writing: 'Don’t speak your first language', write: 'Try to always speak English and ask if you don’t know a word'. If you are feeling really brave, you can even get your students to devise a list of rules for you which you can display on the wall next to theirs.

    6. Make it challenging

    It’s great making your first lesson fun - but there’s nothing more motivating than leaving a new class and feeling like you’ve made a good decision and you are going to learn lots (and you aren’t wasting your time or money). This is especially important for adult learners.

    So, as well as getting to know each other and finding out their needs, teach them something new. This could be 10 new pieces of vocabulary, how to structure a letter or report, or a list of resources they can use at home to practice their English.
