As critical group representatives in public school districts (K-12), superintendents and teacher union presidents have a direct
impact
on the success of education reform programs. Aspects of the superintendent-union president interface were explored by focusing on one ingredient of effective work relations, namely, interpersonal trust. Regression analyses of survey data from 305 superintendents and 293 presidents investigated potential differences across the two samples concerning variables influencing respondents ` willingness to trust the other group representative. For both samples, willingness to trust was influenced primarily by expectations about
the
other group representative's future trustworthy behavior Social judgment factors were important predictors of expectations for both superintendents and presidents. For presidents, personality failed to influence expectations. Perceptions of normative referent groups suggested that superintendents and presidents operate under conflicting intergroup pressures.
