A project update goes out to three offices. In London, it lands perfectly. In São Paulo, someone reads it twice before replying, unsure if “we’d like to revisit this” means the plan is dead or just delayed. In Seoul, nobody replies at all, because asking for clarification feels riskier than staying quiet.
Nothing was lost in translation, exactly. The project update was lost in confidence.
Multiply that moment across a global team, every week, in every language pair, and you start to see why English has quietly moved from a line item in the training budget to something closer to infrastructure, as fundamental to how a company runs as its project management software or its shared calendar.
Most HR and L&D leaders already know their teams are multilingual. Fewer have measured what that actually costs. Research from Grammarly’s 2025 State of Business Communication report puts the price of poor workplace communication at roughly $1.2 trillion a year across US businesses alone, more than $12,000 per employee. Separate industry research on language barriers specifically found that around half of global executives report direct financial losses linked to miscommunication, and large multinationals can lose deals worth millions when a lack of shared language gets in the way at the wrong moment.
This isn’t flagged as a single failure; it’s flagged as the meeting that ran long because one person needed things repeated or the proposal that had to be rewritten multiple times for clarity.
Consider the good idea that was never expressed (in a second language) in front of senior colleagues because it felt too much of a risk!
A study of 1,300 HR and L&D leaders at large international companies found something interesting. Companies with the most advanced language training programs reported nearly double the net profit margin compared to those with the least developed programs: 23% versus 12%. Employees at these companies also felt more engaged at work, and the companies were much more likely to have entered new markets in the last two years.
Of course, just because two things are linked does not mean one causes the other. And no single training programme explains a company’s whole profit margin. Still, the pattern is clear across many companies: treating language skills as a strategic asset often goes hand in hand with stronger business results (and client satisfaction).
When a team needs to improve their English, the first thought is often to focus on grammar drills and vocabulary lists. But that’s usually not where the main problem lies.
The employees who have the hardest time in English-language meetings are usually not those with poor grammar. Instead, they are the ones who understand everything but still hesitate to speak. Creating a clear, timely response in a second language, on the spot and in front of colleagues, is a very different skill from reading a report or writing an email when you have time to think.
The results in performance reviews with comments such as “James could be more assertive” or “Jane needs to contribute more in meetings.” The issue, though, is not that the employee lacks confidence in general; it’s that they lack confidence using English.
Two changes are making this issue more urgent:
Teams are now more spread out, so the casual chats that used to fix small misunderstandings no longer happen.
AI writing tools make it easy for anyone to write correct English quickly. But AI cannot speak up in a live negotiation, read the mood in a room, or build trust with a client on a call. These are human skills, and most training budgets still do not focus on them.
The organisations getting the strongest results tend to share a few things in common. Training is tied to their specific industry and includes business scenarios, intercultural communication, client calls, leadership meetings, cross-team negotiations… the situations employees actually face.
It’s delivered live, with real feedback, rather than through self-paced modules alone. And progress is tracked against outcomes that matter to the business, not just a CEFR level on a certificate.
This is the approach EC Live uses: live, customised English training for teams, designed for your people’s actual roles, industries, and real work situations. The method also gives L&D and HR leaders clear insight into where progress is being made.
Corporate English training becomes essential as soon as a team goes global. It is one of the most effective ways to improve productivity, collaboration, and confidence across a multinational workforce. Organisations that understand and act on this see real results.

The data supports this. Companies with the most advanced language training programs report much higher profit margins, greater employee engagement, and more successful expansion into new markets than those with little or no structured program. Other research also shows that poor workplace communication costs businesses over a trillion dollars a year in lost time and mistakes.
Often, yes. The employees who struggle most in serious English situations are usually not those with weak grammar. Instead, they are the ones who understand everything but still hesitate to speak up. This is a gap in confidence and real-time communication, not fluency, and general English courses rarely address it.
Good corporate English training focuses on real business situations and the skills and language that are needed in that specific organisation and industry. There is no one-size-fits-all solution to corporate English language training.
Ultimately, the success of a training programme is measured by workplace results.
In most cases, the opposite is true. AI makes it easy to write correct English, but it cannot speak up in a live meeting, negotiate with a client, or build trust during a call. These human, real-time skills are more important now than ever.
