Which term best defines the ongoing adjustment process in a client's career life cycle between ages 45 and 64?

The term that best defines the ongoing adjustment process in a client's career life cycle between ages 45 and 64 is "Maintenance." During this stage, individuals typically focus on sustaining and enhancing their established careers rather than exploring new options or experiencing significant turnover. Maintenance involves refining skills, solidifying roles within an organization, and often mentoring others. It is characterized by efforts to achieve personal satisfaction in work and life while ensuring continued professional development.

This period allows individuals to consolidate gains made in previous career stages and may include navigating changes such as organizational changes, adapting to new technologies, or preparing for potential transitions into retirement. In essence, it's about optimizing existing roles and experiences rather than initiating major career shifts, which is why maintenance is the most appropriate term for this age range in the career life cycle.
