Clarity: It is also essential to ensure that the person you are speaking with has completely understood what you have to say. Hence, one should speak very slowly and clearly. If you have a strong ethnic accent, you should make sure that you talk slowly so that the other person gets what you have to say. It is always good to ask, "have you understood?" just in case someone doesn't get what you have to say.
Listen to Others: Most people think of effective communication as a one-way thing. But it is very important to also be a good listener and not just a good talker. Others too often have something to say or to contribute to a discussion hence, listening too, is one of the effective communication skills at work.
Posture and Body Language: They say actions speak louder than words and the same can be considered to be true at the workplace. The body has a language of its own too, and at the workplace, the body ought to be courteous. There are simple things to keep in mind, whether it is wishing everyone 'good morning' at work, or having a courteous smile on your face, being well-dressed in office or sitting erect when someone is talking to you.
