English is a requirement for more jobs in more countries than ever before in human history.
Even 20 or 30 years ago, having a strong grasp of the English language was not as important as it is today.
The actual number of multinational companies in the world is difficult to estimate.
One of the most recent surveys was completed in 2016 by EF Education First, which showed a 25 percent increase in the number of multinationals over the previous 10 years.
In a study by the National Association of Colleges and Employers, 73.4 percent of employers said they wanted job candidates with strong written communication skills.
While the educational system has focused on science, technology, engineering and mathematics, 75 percent of employers stated that there should be a greater emphasis on written communication skills in college.In 28 non-English-speaking countries, 70 percent of the companies surveyed reported that English was important to their business, while 11 percent stated that it was the main language.The disparity in English proficiency among industries has been narrowing, with the gap between the highest and lowest industries reduced nearly by half.If you live in an English-speaking country like the United States, Great Britain, Canada or Australia, your business doesn't just depend on your fluency but also your proficiency in English.Poor grammar and a lean vocabulary can seriously undermine your influence with customers who take good English for granted, and if you plan to take your business overseas, you're as likely to need good English as you are at home.Imagine negotiating a service contract with a multinational company and then finding out that each of their offices have different language requirements and that you would need to communicate with them in English, French, Spanish, Portuguese, Italian and Mandarin.Tsedal Neeley, an associate professor at the Harvard Business School and author of "The Language of Global Success" tells a story of a group of French sales reps who went on a sales call to a French company based in Paris.In fact, only 20 percent of their Tokyo-based engineers are now Japanese.On a global scale, multilingualism in business simply doesn't work.In the past, English was required in global companies only for senior management.Today, companies' clients and suppliers, their technical support teams and their own management can be spread across several countries.
