In the last two decades, public sector labor relations have been chara
cterized by privatization, service cuts, and ad hoc legislation suspen
ding negotiation rights. In this new environment, it seems crucial for
public sector unions to build strength among their membership and to
recruit volunteers to lead their local unions. Keeping this practical
concern in mind, the research proposes an explanatory model of partici
pation in local union leadership position. Based on social psychology
theory, the model suggests that participation in local union leadershi
p depends on an individual's attitude toward the union, on the social
norm, and on that individual's work-related and psychological needs. p
articipation is also associated with other variables such as seniority
, gender, and employment status. The model was tested in a Canadian pu
blic sector union.
