The Empirical Study on the Effect of Family Motivations of Frontline Operators on their In-role and Extra-role Performance

This study employs a comprehensive motivation model as its theoretical foundation to examine the differential effects of family motivation on the role-related and non-role-related performance of frontline operational staff. It introduces organisational constraints, family financial pressure, and job competence as moderating variables to explore the boundary conditions of these differential effects. Focusing on frontline operators in the petrochemical industry, the study employed a two-round questionnaire survey, collecting 211 valid paired questionnaires. Empirical testing was conducted using hierarchical regression in SPSS 26.0 and Mplus7.4 Findings indicate: (1) Family motivation significantly and positively influences both in-role performance (safety performance, task performance) and extra-role performance (organisational citizenship behaviour) among petrochemical frontline operators; (2) Organisational constraints positively moderate the relationship between family motivation and safety performance; (3) Household financial pressure positively moderates the relationship between family motivation and task performance; (4) Job competence positively moderates the relationship between family motivation and organisational citizenship behaviour. This study enriches the understanding of the effects of family motivation on role-related and non-role-related performance and their boundary conditions. It assists enterprises in recognising the critical role of family motivation in stimulating both role-related and non-role-related performance among frontline operators in the petrochemical industry. Furthermore, it facilitates the formulation of differentiated guidance policies at various levels to promote the conversion of family motivation into role-related and non-role-related performance.
