Communication is a complex process that enables the exchange of information, ideas and emotions through different channels, whether verbal or non-verbal in nature. In everyday life, communication is a fundamental element of every social aspect, necessary for interpersonal interaction. It is not only a means, but also a powerful tool that shapes an individual's relationship with the environment and influences his perception of himself and the organizations he is connected with. Business communication in the banking sector is extremely important primarily to retain clients and maintain long-term relationships with them. Bankers need to communicate in an understandable, transparent manner to convey information to clients about their financial products, services, costs and risks. In addition, it is important to adapt communication to different clients, taking into account their individual needs, preferences and level of financial literacy. Quality communication builds a sense of trust and attachment among clients, which is of key importance for the bank's long-term success.
