Childhood and Adulthood Socioeconomic Statuses in Relation to Union Interest: Exploratory Surface Relationships

Abstract

Using response surface methodology for exploratory data, we examined the linear and nonlinear surface relationships between no mobility and mobility in reference to union interest defined by willingness to join a labor union. Analyses were conducted on survey data collected from U.S. nonunion employees (N = 1,010) who indicated their socioeconomic status (SES) in childhood and adulthood in reference to social class, education, and English language/literacy (e.g., language/literacy during childhood, language/literacy now). Surface relationships were mostly linear. For example, among status indicators, a linear surface was found for employees whose childhood and adulthood language/literacy were the same (no mobility): Lower status nonmobile employees showed more union interest than higher status nonmobile employees. In contrast, a nonlinear surface was found for employees whose childhood and adulthood language/literacy were not the same (mobility): Upwardly mobile employees showed less union interest than downwardly mobile employees showed more interest. Details of the surface relationships and future modeling of the relationships in terms of mediational processes are discussed.
