WHEN I joined my present company a couple of years ago, all our local workers conversed with each other in Malay. There was a handful who could speak a little English.
The influx of Nepali workers changed the whole scenario. Almost every worker could converse in simple English and interacted with the foreigners comfortably to complete their daily tasks efficiently.
How was it possible? The Nepalese could only speak in their mother tongue and a little bit of English and our workers had no choice but to talk to them in English in incomplete sentences.
I encouraged most of our workers to continue with their efforts without being shy. Now, I see a marked improvement in their daily conversational English.
This is proof that any language can be learned by mere observation, listening and practice, and talking often without being shy.
