I agree with Shweta, Proper communication is the best tool and ensure your communication is going thru a proper channel. In one of the organisation where I was working we had to retrench the workers, that organisation had a voilent IR in the past, but we had communicated to the employees from the stage of filing application. The workers were uneasy, but sure there was no single voilence case in this organisation after filing or after retrenching the workers. Thus I think Communication is an Important tool,
