Age-related differences in employee absenteeism: A meta-analysis.

Meta-analyses were performed on 34 samples that included correlations of the age and employee absenteeism relationship. Samples were categorized into 2 groups for voluntary absenteeism and involuntary absenteeism based on the frequency index and the time-lost index, respectively. Results indicated that both voluntary and involuntary absence are inversely related to age. Unexplained variance remained for each of the absence measures after variance due to sampling error and measurement unreliability was statistically estimated. Work demand was negatively associated with age, but not in the expected direction. Work demand did not moderate the age-absence relationship for either voluntary or involuntary absence. Sex moderated the relationship between age and voluntary absenteeism only. For men, the relationships were negative; for women, they did not differ significantly from 0. Implications for research and human resource management practices regarding aging and absenteeism are discussed.
