This study uses longitudinal data on nearly 300 American employers ove
r the period 1955-85 to analyze the adoption of disciplinary hearings
and grievance procedures for nonunion salaried and hourly employees. H
ypotheses are developed from an institutional perspective that focuses
, first, on uncertainty arising from government mandates concerning eq
ual employment opportunity and affirmative action and, second, on the
role of the human relations professions in constructing employment-rel
ations law and prescribing models of compliance. Event-history techniq
ues are used to test these hypotheses against competing arguments conc
erning the internal structure and labor market position of employing o
rganizations. Results on all outcomes strongly support the institution
alist model.
