There is a broad literature linking social support to health, which includes evidence that social support from supervisors is positively associated with worker health. In addition, once workers experience a health concern, supervisors may play a key role in supporting workers, keeping them on the job despite health issues. However, there are few studies that investigate the day-to-day strategies supervisors utilize to support their workers and help them stay on the job despite health concerns. The study presented in this paper addresses this gap. Thirty-two supervisors from three companies were interviewed about their experiences supporting and accommodating skilled workers during flare-ups of a health condition. A grounded theory approach was used to analyze the text data and identify themes. Three key themes emerged from the data: 1) workplace policies provide the structure for mutual problem solving; 2) communication skills and existing relationships increase supervisor effectiveness; and 3) strategies were aimed at individual, interpersonal, and institutional supports. Supervisors regularly interact with workers to support and accommodate episodes of illness or pain. While supervisors employ novel and effective strategies, there is an opportunity to improve the range of strategies, better understand and utilize company policies, and facilitate appropriate communication about worker health concerns. 相似文献

This article applies the testing procedures for measurement invariance using multigroup confirmatory factor analysis (MGCFA).
It illustrates these procedures by investigating the factorial structure and invariance of the Portraits Value Questionnaire
(PVQ, Schwartz et al.: J. Cross Cult. Psychol. 32(5), 519–542 (2001)) across three education groups in a population sample (N = 1,677). The PVQ measures 10 basic values that Schwartz postulates to comprehensively describe the human values recognized
in all societies (achievement, hedonism, self-direction, benevolence, conformity, security, stimulation, power, tradition
and universalism). We also estimate and compare the latent means of the three education groups. The analyses show partial
invariance for most of the 10 values and parameters. As expected, the latent means show that less educated respondents attribute
more importance to security, tradition, and conformity values. 相似文献
