The Interplay between Job Control, SOC Strategies, and Age in SustainingWork Ability in a Sample of Administrative Employees

In recent years, the average age of workers has risen. Because of that, work ability is reducing in many sectors, especially in a public context. Given the above, it is necessary to investigate the individual and organisational resources that can play a role in the protection of work ability. This study investigates the work ability of administrative workers, examines selection, optimisation, and compensation (SOC) as a form of mediation between job control and work ability, and explores the relationship of job control, age, work ability, and SOC strategies via moderated mediation models. The findings indicate that job control, SOC strategies, and age correlate to work ability, but the effect of these factors is different. Job control and SOC strategies are positively related to work ability, and job control positively relates to the use of optimisation and compensation. However, only optimisation and compensation strategies mediate the association between job control and work ability. Finally, age moderates the effect of job control on work ability. The findings suggest that interventions, such as SOC training, promotion, and job control, may help to sustain work ability among elderly administrative workers.
