This research examines leader-member exchange (LMX) at the group level as a moderator of the relationships between demographic (i.e., race, age, gender) and tenure diversity and group turnover. Drawing primarily from LMX, social categorization, and expectation states theories, we hypothesized that through the pattern of LMX relationships that they develop with followers, group managers influence inclusion and status differentials within groups such that the positive relationship between diversity and group turnover will be weaker when the group mean on LMX is high or when group differentiation on LMX is low. Results from a sample of supermarket departments (N = 348) yielded general support for the study hypotheses. We also found evidence for a 3-way interaction involving demographic diversity, LMX mean, and LMX differentiation such that the interaction between demographic diversity and LMX differentiation was only significant when LMX mean was high. These findings highlight the important role that leaders play in influencing the relationship between diversity and turnover through the patterns of inclusion that they create in their units.
这项研究考察了群体层面的领导-成员交换(LMX)作为人口统计学(即种族、年龄、性别)和任期多样性与群体离职之间关系的调节变量。本研究主要借鉴 LMX、社会分类和期望状态理论,假设群体经理通过与下属建立的 LMX 关系模式,影响群体内部的包容和地位差异,从而当群体 LMX 的平均值较高或 LMX 差异较低时,多样性与群体离职之间的正相关关系会减弱。对超市部门(N=348)的样本进行的分析结果普遍支持了研究假设。我们还发现了一个涉及人口统计学多样性、LMX 平均值和 LMX 差异化的 3 -way 交互作用的证据,即只有当 LMX 平均值较高时,人口统计学多样性和 LMX 差异化之间的交互作用才具有显著性。这些发现强调了领导者在通过他们在单位中创造的包容模式来影响多样性与离职之间关系方面所扮演的重要角色。
