Final answer:
The claim that workers nearing retirement necessarily demonstrate a decreased level of work commitment and value observance is false, as individual goals and physical abilities shape retirement approaches, allowing for meaningful engagement in selective activities. The statement is false.
Step-by-step explanation:
The statement that workers nearing retirement show a decreased level of commitment to work and observance of values about work is false according to the information provided.
Rather, the approach to work and retirement is influenced by an individual's goals and physical capabilities.
Disengagement theory does postulate a withdrawal of aging individuals from societal roles and engagement, but this is not viewed solely in negative terms.
It allows people to conserve energy and engage meaningfully in a select range of activities that are aligned with their capabilities and values.
For example, an aging professor may enter a phased retirement, continuing to teach on a limited basis that accommodates personal physical limitations and ongoing commitment to the discipline.
