This study examines the effect of objective and subjective career plat
eau on the attitudes and behavior at work of a population of 2183 mana
gers from three sectors of the Canada economy. Our study corroborates
others that have found that ''plateaued'' and ''non-plateaued'' indivi
duals respond differently to their work environment. Our results indic
ate that career plateau is associated with a number of consequences, o
nce we have controlled for the effects of a number of personal charact
eristics such as age, sex, education, seniority and hierarchical level
. The study also shows that the explanatory power of the subjective ca
reer plateau is significantly greater than that of objective career pl
ateau. The explained variance in reactions is increased by at most 1%
with the introduction of objective plateau for career satisfaction, wh
ile introducing subjective plateau into the model has the effect of in
creasing its explanatory power by 12%.
