I agree with Mr. Santosh Iyer's statement. Additionally, try practicing speaking English first within your familiar circle, such as with your friends and relatives. Even if you make mistakes, they will not laugh at you, and you will always have the opportunity to enhance your speaking skills. Over time, you will build confidence in speaking English at the office. Don't hold yourself back. Every day, expand your vocabulary by learning new words.
Hope this advice helps, and best of luck!
