This is communication. As teachers of foreign languages for corporate clients, Zara and her colleagues at Workplace Languages help close communication gaps. Because the Spanish-speaking population is now the largest ethnic group in the U.S., they've been called on to help managers reach out to this largely untapped source of new clients/customers and also new employees. The language skills not only help businesses to grow but also have lessened workplace stress, increased productivity, and helped workers feel more respected and motivated.
