Nowadays, trust is perceived as one of the key factors that can build an organization's competitive advantage, increase the efficiency of its functioning and ability to develop. It can be expected that shaping trust in an organisation will lead to improvements in various aspects of its functioning, especially effectiveness. This issue has not yet been the object of comprehensive scientific research. Hence, this study tackles the issue of the impact of trust on an organization's outcomes. At the same time, two basic categories of trust are distinguished: global (attitudinal/affective) trust (regarding the belief that people in general are trustworthy) and specific (situational/cognitive) trust (modified by an individual's experience).

The research covers organisations functioning in Poland and is based on a questionnaire. (original abstract
