When employees use information and communication technologies, they may experience work overload, uncertainty, incompatibility, insecurity, confusion, and difficulty understanding. This is because not every individual has the same understanding ability, personality, emotions, and thoughts. Therefore, they may not be able to adapt to understanding new technological developments and using tools and equipment, and this can cause stress. This type of stress, which arises in individuals due to technology use and the difficulty they experience in using technology, is called technostress, and it can be said that if technostress is not addressed, it will lead to significant problems in terms of effectiveness and efficiency for both individuals and organizations. On the other hand, technostress can also lead to negative emotional consequences for individuals. Therefore, it is important for organizational managers and individuals to identify the causes of technostress and develop strategies to combat it.
