The workforce is a social environment where particular skills are essential in order for employees to perform well, have a competitive edge and succeed in their careers. Interpersonal communication is one of the skills needed in every type of workplace setting. The ability to actively and empathetically listen, adapt communication style according to others and situations, confirm others in communication, resolve conflict, manage tone in writing and effectively communicate in a group are all crucial skills for employees that require exceptional interpersonal communication. However, constructivism theory suggests that due to variances in cognition, not everyone is able to communicate interpersonally at the same level. This thesis project examines the history of constructivism theory, interpersonal communication and its relevance in the workplace and interpersonal communication training to further study how they all interrelate. The project builds upon constructivism theory and phenomenological philosophy to develop an interpersonal communication training curriculum for adult employees that provides improvement in cognition by aiding employees in awareness of possible deficiencies and using skills to overcome them and interpersonally communicate effectively. The projects' goal is to decrease the divide in interpersonal communication differences in employees so that all employees have a stronger possibility of job satisfaction and have the opportunity to excel in their careers.
