“…Furthermore, evidence of previous studies offers convincing rationale for the inclusion of the primary factors within the working model (see Figure 1) shown in this article. For example, earlier transportation studies investigated some elements of driver-dispatcher relations (Keller & Ozment, 1999;Taylor, 1991), job satisfaction and attitudes (McElroy, Rodriguez, Griffin, Morrow, & Wilson, 1993), relationships with customers, driver turnover, and driver performance (Keller, 2002), human resource management practices that influence quit rates (Min & Lambert, 2002;Shaw, Delery, Jenkins, & Gupta, 1998), and other variables such as fringe benefits, training, career development, time home, salary, bonuses, driver performance, education, and other demographic variables (Gaertner, 2000;Min & Lambert, 2002;Nafukho & Hinton, 2003;Nafukho, Hinton, & Graham, 2007;Richard, LeMay, & Taylor, 1995).…”
