Taking human resource policy solutions to retain older workers in the labour force longer is one of the measures which can prevent the economy as well as the individual households from the excess burden of old age dependents. To create such an environment, understanding the age-related factors of older workers’ motivation on employment is vital. This study aims to investigate the factors, which explain the choice of livelihood by the older labour force aged 50 years and above using the Sri Lanka Labour Force Survey data 2013.
