Introduction
The study of ageing workforce in an organization has been a recently emerging area
of research interest for the academicians, stemming from the realization that as
the number of older employees are expected to increase vastly in the near future, organizational
performance is likely to be influenced by factors associated with ageing. Therefore,
more attention needs to be devoted to the problems of older workers in organizations as
organizational performance is likely to be influenced by ageing.
CONCEPT OF AGEING
Ageing is the accumulation of changes in a person over time. Ageing in humans is not
only associated with the chronological years spent since birth, but refers to a
multidimensional process of physical, psychological, and social change. Furthermore, in general,
ageing is associated with decline in various capacities, both physical and mental, despite
the fact that actual empirical evidences fail to equivocally support this notion.
Cleveland and Lim (2007) have listed a number of approaches to define an older worker's age and
they categorize them on the basis of two measures, viz., person-based age measures and
context-based age measures.
Chronological or calendar age is the most widespread person-based measure in research on older
workers, but it provides a very narrow view of the ageing,
