Branch Closures, Banking Consolidation, and the Psychological Contract: An Integrative Review and Research Agenda

The downsizing of branch networks shapes the consolidation of the banking sector, yet its consequences for the employees affected remain insufficiently systematized. This study unites previously unconnected research streams on branch closures, workforce reductions, and the psychological contract in an integrative, theory-building review with systematic safeguards in search, selection, appraisal, and synthesis. Based on 24 documented search runs, 139 sources were entered into an evidence matrix, coded as banking, financial-sector, or transferable evidence, and appraised in two stages. The synthesis condenses the findings into seven clusters. Closures act as contract-relevant events from the moment of announcement, their consequences vary by degree of affectedness, and justice and trust judgments form the central mediating mechanisms between perceived breach and attitudinal and behavioral outcomes. Communication, leadership, and participation emerge as design levers, remediation works contingent on substance and timeliness, and contract trajectories show nonlinear recovery paths. The synthesis yields a process-oriented framework with five phases, eight moderators, and three feedback loops, from which ten testable propositions follow. Two gap findings carry the research agenda: the experience of branch closures by branch workforces is largely unstudied, and the institutional differentiation of the German three-pillar system (private, savings, and cooperative banks) is contract-theoretically untested. The agenda specifies eight directions, including multi-wave longitudinal studies from announcement onward, comparison-group designs for transferred, remaining, and departing employees, and multilevel tests of pillar moderation. Practically, announcement design, procedural justice, respectful delivery, and timely, substantive remediation co-determine whether consolidation damages the employment relationship or renews it as a renegotiated contract.
