If businesses are to effectively compete in a global economy, they must learn to deal with other cultures on their own terms. Companies that plan to do business abroad therefore have a dire need for bilingual or multilingual employees. Businesses that intend to compete internationally need employees who can competently communicate in the locales where they do business. Employees who speak one language can communicate only with people who speak that same language.
Business is not the only area of employment where language competencies are needed, however. Multiple government agencies, the travel industry, engineering, communications, the field of education, international law, economics, public policy, publishing, advertising, entertainment, scientific research, and a broad array of service sectors all have needs for people with foreign language skills.
Whatever your career goals, knowing a language certainly won’t hurt your employability. Chances are that knowing languages will open up employment opportunities that you would not have had otherwise. And you will be able to command a greater salary in the workplace. All else being equal, knowing languages gives you an edge over monolingual applicants competing for the same jobs.
