It has been observed that poor communication leads to confusions and misunderstandings. The communication has to be precise and relevant. One should not play with words and be very specific about his expectations from his fellow workers as well as the organization. If you are not very happy with your colleague’s proposal, don’t keep things to yourself. Voice your opinion and do express your displeasure. It will definitely prevent a conflict among employees later and improve the relations among them. Be straightforward. Don’t pretend things just to please your boss. If you find anything unacceptable, discuss with your superior but in a polite way.
