This paper investigates how both attitudes and normative pressures influenced the voting decisions of public university clerical workers in a December 1984 union representation election. Not surprisingly, the voters' attitudes, shaped by the results they expected to follow from union certification and their evaluation of those results as good or bad, appear to have been an important determinant of voting intentions and, in turn, actual votes. Also influential, although less so, was normative pressure, a function of how the voters thought others (family, co-workers, other clericals, supervisors, and other management staff) wished them to vote and how strongly they were inclined to satisfy those wishes.
