In order to know how UNISON makes sure that it communicates well within the company and to the outside world, the process is best revealed through the Shannon-Weaver model (1947).
People working within UNISON try to reduce all the barriers or 'noise' to make sure they communicate clearly. This involves a transmitter sending messages to receivers. A transmitter should put data into a form the receiver can understand, such as a written or visual point. This is known as encoding. The medium is then chosen this might be a letter, e-mail or website. The receivers then translate the message through a process of decoding.
Though a message flows from the sender to receivers, there is no guarantee the receivers will either get or even understand it. This is because the process may involve communication difficulties. These problems are known as 'noise' and they may weaken or destroy the message that is being sent. For example, noise would occur if a message was hard to understand or used badly chosen language.
Within a trade union, a policy or plan comes from the members. The role of employees at UNISON is to take it forward and put it into action. It is through helpful contact, both internally and externally, that this is able to happen.
