Voting in an Officer Election: Testing a model in a multi-site local

We test a model based on social exchange theory to explain the patterns of membership voting in a local union officer election. Survey data from members and stewards aggregated by 55 voting units, when combined with the control variable, explained 46 percent of the variance in the incumbent president's re-election. A greater percentage of member votes for the incumbent president were related to higher union loyalty, higher confidence in the grievance procedure, better union-management relations, and more positive perceptions of the union contract, findings that support our model of membership voting.
