I develop a theory of the relationship between government actions and union political protest that uses conjunctures and structures to explain government- related factors which influence union political protest. Conjunctures are dramatic political developments that have the potential to tilt the status quo in industrial relations against, or in favor of, union vested interests. Here, the core conjunctures are significant debts and budget deficits concurrent with governments preaching severe budget cuts and public sector restructuring that, if implemented, can undercut unions. Structures are the policy tools that governments use to implement their agendas. Together, conjunctures and structures constitute a distinct government logic that influences the likelihood of union protest.
