The literature addressing gender-based discrimination in promotion decision
s has primarily focused on case studies of Fortune 500 companies or scenari
os in which managers are asked to make simulated promotion decisions. Such
studies ave limited in both scope and generalizability. This research attem
pts to overcome these limitations by examining a large, random sample of fe
male and male workers. Using survival analysis, we explore the period of ti
me from the year of hire to the year promotion to supervisor is achieved. A
voiding bias that may be associated with analyses pertaining to a particula
r type of organization or sector of the economy, this investigation focuses
on a particular career moment-procession io a primary rung of the career l
adder. Findings support the existence of significant pro-male bias in promo
tion decisions unattributable to differences in ti,ne on the job, education
, or parenting responsibilities.
