THE IMPACT OF WORKING CONDITIONS ON WORK AND FAMILY INTERFACE Eduardo Infante and Manuel Marín, University of Sevilla, Spain Paper presented to the Community, Work, and Family Conference, Manchester, 16-18 March, 2005 Abstract The present paper analysed the impact of working conditions on to work and family interface among 167 workers from two big public companies dealing with national civil defence (n=67) and higher education (n=100). Specifically, we have considered the additive influence towards incrementing work-family conflict (WFC) of a number of structural working conditions. Working conditions were clustered in two big groups of work-family demands, that is, (1) time-pressure (frequent trips, working days/hours per week, home-work distance, flexible work schedule, work turnover, and having to work on weekends), and (2) hierarchical pressure (labour promotion, moonlighting, organizational position, experience, money income, and type of contract). We resumed data obtained using self-report measurements on personal and organizational status and WFC based on Carlson, Kacmar and William (2000). As the literature has been confuse on these relationships (White, 1999; Brannen & Nilsen, 2001; Barnett & Gareis, 2002; Rau & Hyland, 2002) the mediated influence of employee sex and the work-family balance phase are also analysed. Because the gender role socialization in women is said to be inadequate for work performance (Dexter, 1985; Babin & Boles, 1998) we expected clearer and stronger relationships between structural working conditions and WFC among women rather than men. Even more, sex differences in the emergence of WFC through various working conditions is understood at the light of multiple role literature (Gutek, Repetti & Silver, 1988; Barnett, 1999; Wethington, Moen, Glasgow & Pillemer, 2000). Therefore, our latest results indicate that women suffer higher WFC than men when working conditions are related to time rather than hierarchical pressures.
