Each company has its own culture, which could be based on a mission statement, possibly a company motto, but mostly from the manner in which the executive and managerial staff conduct themselves and the manner in which the rest of the staff is treated by these particular staff members. So, internal communication is constructed as an upside down triangle and works itself from the head of a company down to its cleaning staff. If a CEO communicates well with his employees and he treats his employees with respect, then the rest of the company should be able to apply the methods and interactions appropriately.
Unfortunately, this is not always the case as individuals are initially taught how to communicate by parents and schools. So essentially, communication is a learnt behavior, which means that you are provided with a strong basis of how to communicate, although you are able to change and learn a new way of communicating and improving on this previous knowledge. This act should however, be acknowledged and accepted by the person learning this adjusted and new way of communicating in order for the transition to be smooth and successful.
Assuming that the internal communication is professional and acceptable, this will attract more clients to the company, customer service will improve and the employees will be happy within their current positions. However, this is not the case in many companies.
Currently, companies are experiencing certain issues within human resources departments, employees do not address one another with respect and an understanding that is required. There are constant problems where employees talk behind each others backs, either to vindictively take over that individual's position or alternatively because the individual is simply not performing adequately within the position.
Either way a company's employees needs to work together as a team all the time! Each person, no matter their job description, serves a purpose within the company and without that person the company is not the same. In the theatrical industry, Konstantin Stanislavsky said that, "There are no small parts only small actors." From the stage manager, stage and set designer to the tea lady, cleaner, actor and prompter, each person involved in the culmination of the final production must put all their effort into the final goal. Without this, the end result is at best mediocre and at worst a dismal failure.
