Drawing upon the cases collected from 2 companies, this study attempts to identify the bases of trust which the workers have in their superiors. 13 trust bases and 12 distrust bases were elicited from 580 and 430 cases, respectively. Most of the bases seemed to be characterized by a exchange of activated inner-mind between the workers and their superiors. When the pairing of bases between trust and distrust were done in terms of their concent similarity, most of the bases were paired with two opposite polars of a diimension, but each dimension appeared to make more contribution to generating either trust or distrust. Finally, the implications, limitations, and directions for future research that the results of this study would have were discussed.
