Discrimination of older peers is associated with workplace age discrimination: moderation by occupational health literacy

Background – Workplace Age Discrimination Experienced (WADE) can be disorientating and detrimental to well-being. Hence, older employees would like to avoid it, but those who experience it may discriminate against their older peers. WADE may be associated with Age Discrimination of Peers (ADP), and this relationship can be moderated by Occupational Health Literacy (OHL). Aim – This study aimed to assess the association of WADE with ADP and to ascertain whether this relationship is moderated by OHL. Methods – A cross-sectional design based on a research-reporting checklist was adopted. Measures against confounding and common methods bias was utlised to avoid or minimise bias. The participants were 1025 middle-aged and older employees (average age = 58 years) who were permanent residents of Accra, Ghana. Hierarchical Linear Regression (HLR) analysis was utilised to analyse the data. Curve estimation was among the methods used to assess assumptions governing HLR analysis. Results – WADE and OHL were positively associated with ADP, but OHL was negatively associated with WADE in the ultimate models incorporating the covariates. WADE was more positively associated with ADP at moderate and higher OHL, which signified positive moderation of the WADE-ADP relationship by OHL. Conclusion – Older employees who experience higher age discrimination at work are more likely to discriminate against peers. OHL can be associated with lower WADE but higher ADP. Qualitative studies are needed to understand why OHL may be related to higher ADP.
