This article develops a framework for analyzing illegal public sector strik
es that explains observed patterns of behaviour of employees, unions, manag
ers, and third parties. If is found that no-strike laws diminish such posit
ive effects of right-to-strike bargaining systems as eliciting information,
adjusting expectations and providing catharsis. A new theoretical outline
helps understand and explain such illegal strike characteristics as the sud
denness of strike development, the rank-and-file nature, lack of union cont
rol, conflict without clearly defined union objectives, and breakdown of th
e conflict regulation process by neutral agencies. Three policy issues emer
ge: some conflict could have been avoided with a broader scope of bargainin
g (PATCO and Ontario jail guards); mandatory and more responsive third part
y procedures should be legislatively provided. and such information about w
orker discontent as grievance usage should be made available to dispute set
tlement agencies and mediators before conflict escalates out of control.
