Drawing hypotheses from a theory of lifespan development called selective optimization with compensation (SOC, Baltes & Baltes, 1990; Baltes, Staudinger, & Lindenberger, 1999), the study explored the degree to which employee age moderates the relationship between employee affective commitment and satisfaction with various high commitment human resource practices (HCHRPs; e.g., providing training, opportunity for advancement, work/life balance). In addition, as exploratory hypotheses, the study also tested whether other employee-level variables such as gender, job tenure, and job type also serve as moderators of the HCHRP-affective commitment relationship. Customer-facing employees (N = 6,360) representing three job types (O*NET titles: Shipping, Receiving, and Traffic Clerks; Truck and Delivery Services Drivers; Couriers and Messengers) from an international transportation company completed an eight-item version of the Organizational Commitment Questionnaire (OCQ, Mowday, Steers, & Porter, 1979) and a questionnaire assessing their satisfaction with various HCHRPs offered by their organization. Path analyses assessed the significance of two-way interactions concerning age (i.e., age-by-HCHRP) and job tenure (i.e., tenure-by- HCHRP), as well as three way interactions concerning gender (i.e., gender-by-age-by- HCHRP) and job type (i.e., job type-by-age-by-HCHRP). Results show that, although there was a strong overall correlation between affective commitment and satisfaction with HCHRPs (r = .66), employee age was a significant moderator of only the relationships between affective commitment and maintenance-related HCHRPs (e.g., life/work balance, job security) and not of development-related HCHRPS (e.g., training opportunities, opportunities for advancement). More importantly, although the moderation effects were statistically significant, the effect size of every moderation was small, suggesting from a practical perspective that employee age is not a characteristic that organizations need to consider when making strategic decisions about HCHRPs.
