Negative outcomes of ageism in the context of the Canadian labor market are well documented. Older workers remain the target of age-based stereotypes and attitudes on the part of employers. This study aims at assessing (1) the extent to which quality and quantity intergroup contacts between younger and older workers as well as knowledge-sharing practices reduce ageist attitudes, in turn (2) how a decrease in ageist attitudes increase the level of workers’ engagement and intentions to remain in the organization. Data were collected from 603 Canadian workers (aged 18 to 68 years old) from private and public organizations using an online survey measuring concepts under study. Results of a path analysis suggest that intergroup contacts and knowledge-sharing practices are associated with positive attitudes about older workers. More so, positive attitudes about older workers generate higher levels of work engagement, which in turn are associated with stronger intentions to remain with the organization. However, positive attitudes about older workers had no effect on intentions to remain in the workplace. Results are discussed in light of the intergroup contact theory.
Previous studies suggest that intergroup contact has a positive effect on older workers’ perception of ageism and satisfaction. This study aims at assessing such relationships amongst Canadian younger workers. Precisely, in light of the intergroup contact theory (ICT), it was first hypothesized that a positive perception of intergenerational workplace climate (IWC) and knowledge sharing practices (KSP) increase younger workers’ awareness of ageist behaviors targeting older peers. Second, it was hypothesized that such awareness has a positive effect on young workers’ level of satisfaction. Relying on a cross-sectional design composed of 612 participants, path analysis was conducted. Findings suggest that whereas KSP increases younger workers’ awareness of ageist behaviors towards older workers, this is not the case for IWC. On the other hand, both IWC and KSP have a direct and positive impact on younger workers’ level of satisfaction. Theoretical and practical implications of findings are discussed.
The adolescence period, marked by sexual and brain maturation, has shown sensitivity to various environmental disruptors. Exposure to the xenoestrogen bisphenol A (BPA) is known to alter physiological and behavioral responses although its role at this critical period remains largely unknown. Recent research further suggests biochemical and genomic effects of BPA to be mitigated by various natural compounds, while effects on behavior have not been examined. This study aimed to characterize (1) the effects of dietary BPA during adolescence on endogenous corticosterone (CORT) secretion, emotional behavior, and testosterone (T) in adulthood, and (2) the impact of combined exposure to BPA with hop extracts (Hop), a phytoestrogen with anxiolytic properties. To do so, four groups of male Wistar rats [postnatal day (PND) 28] were administered corn oil (control), BPA (40 mg/kg), hops (40 mg/kg), or BPA-hops by oral gavage for 21 days (PND 28–48). Blood droplets collected on PND 28, 48, and 71 served to measure CORT and T changes. As adults, rats were tested in the elevated plus maze (EPM), the social interaction test, and the forced swim test. Our findings demonstrated elevated anxiety and a trend toward depressive-like behaviors in BPA- compared to hops-exposed rats. However, BPA intake had no impact on basal CORT levels, or adulthood T secretion and sociability. Of note, BPA's anxiogenic effect manifested through decreased EPM open arm entries was abolished by hops co-supplementation. Together, our observations suggest the adolescence period to be less sensitive to deleterious effects of BPA than what has been reported upon gestational and perinatal exposure.
Ageism toward older workers is prevalent in the labor market. The present study aimed to understand psychosocial mechanisms that may counteract this form of discrimination and help retain workers in the labor force. Using a sample of 500 Canadian younger and older workers, this study tested a model hypothesizing that intergenerational contacts and knowledge sharing practices can reduce ageist views about older adults and age-based discrimination against one’s own group, and in turn, enhance work engagement and intentions to remain in the workplace. The final model shows that knowledge sharing practices mediate the relationship between intergroup contacts and positive views about older workers as well as age-based discrimination. It also suggests that low levels of age-based discrimination increase work engagement and intentions to remain in the organization for workers of all ages. Practice and policy implications are discussed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
