Limitations and future study
This study has several limitations. The same participants in the study rate the predictor and criterion variables at one point in time, which makes the study vulnerable to common method variance (CMV). If common method variance is not controlled properly, it may diminish the reliability and validity of any scale used in the study (Min et al., 2016). Although approaches to reduce possible common method variance were implemented in developing the survey instrument, processing data collection, and additional statistical checks (Harmon’s singlefactor test and an unmeasured latent method factor approach), data from the same participants may still represent a limitation. The current study used proximal separation, but using temporal separation (collecting data at two different times with an appropriate lag time) and/or psychological separation would be helpful in reducing CMV (Podsakoff et al., 2012) in future studies. In addition, Min et al. (2016) recommended employing different sources for independent and dependent variables. Using multiple statistical controls such as combining Harman’s single-factor test and an unmeasured latent method factor or conducting the CFA market technique is also recommended to hospitality researchers to control the impact of CMV (Min et al., 2016). A limitation is also the generalizability of the findings as the sample represents hospitality employees working within the same US corporation. Therefore, future research should be conducted in a number of different hospitality corporations to enhance external validity. In addition, organizational hierarchy was examined only at two levels: frontline employees and managers. Future research should consider additional levels of hierarchy, such as frontline, middle, and senior managers, along with direct service employees. Also, the impact of organizational hierarchy on the relationships in the model may be influenced by workplace culture and, thus, workplace cultureis worth examining in relation to organizational hierarchy.
