The technological stress factor is more evident in the aviation industry, which uses high and rapidly changing technology, especially for technical employees. The purpose of this research is to determine the effect of technostress levels of aviation industry employees on their decision-making styles and to investigate the regulatory effects of job insecurity perception, which is of great importance for businesses and employees in this effect. The research universe has been determined as the technical personnel in the airline companies operating in Turkey. At all, 402 questionnaires were considered valid and included in the 25th data analysis of SPSS. It was determined that technological stress was statistically significantly related to rational, intuitive, avoidant and impulsive decision making. Meanwhile, each decision-making style and the dimensions of job insecurity perception separately have significant moderator roles. Finally, it was revealed that all technostress dimensions, except for the techno-invasion dimension, were statistically significantly correlated with at least one decision-making style. In the research, suggestions were made for the effects of changes in employee decision-making styles and perceptions of job insecurity as a result of the effects of technostress, and the results were tried to be explained with aviation industry dynamics and theoretical literature.
