“…Among the factors investigated are circadian dysrhythmia, recycled air, fatigue, shifting work schedules, radiation exposure, and the lifting and handling of heavy objects (Ballard, Lagorio, De Angelis, & Verdecchia, 2000; Dresel & Boutros, 2001; Griffiths & Powell, 2012; Lauria, Ballard, Caldora, Mazzani, & Verdecchia, 2006; Schaub et al, 2007; Sharam, 2007; Suvanto, Partinen, Harma, & Ilmarinen, 1990). Other research has examined how aspects of the job—extended time away from home, irregular work schedules, long hours, and difficult passengers— contribute to work-related stress, psychological well-being, and job dissatisfaction (Avers, King, Nesthus, Thomas, & Banks, 2009; Avers et al, 2011; Gunnarsdottir, Sveinsdottir, Bernburg, Fridriksdottir, & Tomasson, 2006; Liang & Hsieh, 2005; Salinger, Jesilow, Pontell, & Geis, 1985). A few studies address organizational factors—the lack of a clear career path, limited job resources, and lack of immediate supervision—that contribute to stress and turnover (Chen & Chen, 2012; Liang & Hsieh, 2005).…”
