: Survey data concerning the incidence of serious illness before and after retirement are analysed in two ways, (i) by comparison of groups of retired men with groups of men in the last ten years of their working lives; (ii) by examining and comparing the trends over time before and after retirement. Whereas the first method would lead to a conclusion that there is no difference between retired and working men, the second method shows a distinct drop in the incidence of serious illness in the two years following retirement and a slower rate of increase thereafter. It is concluded that retirement is associated with a substantial lowering in the incidence of serious illness. 相似文献

Although we know that high‐quality employee–organization relationships are beneficial, these relationships are complex and not fully understood, especially among employees of nonprofit organizations. In particular, we know little about how these employees perceive trust, which may overlook an important contributor to effective management. We begin to address this issue by testing a new theoretical model that conceptualizes perceived insider status, psychological ownership, and organizational identification as foundations for the perception of justice and subsequent trust. Our results indicate that psychological ownership and perceived insider status relate to trust through procedural and interpersonal justice. These results contrast those typically found in for‐profit contexts in that organizational identification did not predict justice and that distributive and informational justice did not predict trust. 相似文献
