The Construct of Job Insecurity at Multiple Levels: Implications for Its Conceptualization and Theory Development.

Over the years, job insecurity has accumulated important scholarly work. As a result, research has identified multiple constructs that involve employees' concerns about job loss. Most of these are individual-level constructs (e.g., subjective and objective job insecurity), but, recently, an incipient body of literature has adopted a multilevel perspective by understanding job insecurity as a collective phenomenon (e.g., job insecurity climate, strength climate, downsizing or temporary hiring strategies). Furthermore, these constructs at different levels are underpinned by shared theoretical frameworks, such as stress theory or psychological contract theory. However, all this literature fails to present an integrative framework that contains the functional relationship for mapping job insecurity constructs across levels. Accordingly, the present study aims to examine job insecurity from a multilevel perspective, specifically by conceptualizing job insecurity at the individual level-understood as subjective and objective job insecurity-and at the organizational level, understood as job instability in an organization, job insecurity climate, and climate strength. The methodology of multilevel construct validation proposed by Chen, Mathieu and Bliese (2005) was applied; thus, (1) job insecurity were defined at each relevant level of analysis; (2) its nature and structure was specified at higher levels of analysis; (3) psychometric properties were tested across and/or at different levels of analysis; (4) the extent to which job insecurity varies between levels of analysis was estimated; and (5) the function of job insecurity was tested across different levels of analysis. The results showed significant relationships among these, and were related to an organizational antecedent (e.g., organization nature) and organizational and individual outcomes (collective and individual job satisfaction) in two European samples: Austria and Spain. Accordingly, this study exposed the multilevel validity of job insecurity constructs through an integrative framework in order to advance in the area of job insecurity theory and practice. The contributions and implications to job insecurity research and other multilevel research are discussed.
