For many years, career success was mostly viewed as a linear path, often compared to climbing a ladder. Moving up in the same field, advancing within the same function, earning titles in sequence, and showing an uninterrupted career path on a resume were seen as key signs of a strong professional profile. Today, this view is giving way to a more flexible, layered, and experience driven understanding of career development.
At the center of this shift is the concept of a “portfolio career.” A portfolio career means building one’s working life not around a single title, company, or income source, but around a range of skills, projects, industries, and experiences. This does not simply mean freelancing or having a side job. More broadly, it means diversifying one’s career capital, creating value in different areas, and no longer seeing professional growth as tied to a single corporate ladder.
SHRM’s 2026 article, “The Rise of Portfolio Careers Reshapes the Workforce,” highlights how portfolio careers are changing the workforce as employees move toward different ways of working. Economic uncertainty, technological transformation, the impact of AI on roles, and employees’ growing demand for flexibility are making career planning more dynamic.
According to research by ACCA, a global professional body for accounting and finance professionals, 51% of respondents believe flexible career paths will replace linear career paths within the next 10 years. This data shows that the old assumption that a career must follow one fixed route is becoming weaker. In this new era, growth is no longer limited to promotion. Experiencing different functions, building new skills, working on project based assignments, and creating value across multiple areas are also becoming parts of career progress.
This shift is not limited to mid-level or specialist roles. Even the path to becoming a CEO is increasingly shaped by diverse experiences, sector transitions, and cross-functional expertise. We explored this topic in more detail in our latest HBR Türkiye article. Those who want to understand this transformation through the lens of leadership careers can also read more in that article.
A portfolio career should not be seen only as a way to describe today’s flexible work models. It should also be read as an important sign of how the strong professional profile of the future is taking shape. Career value is no longer defined by following a single upward path, but by how meaningfully a person brings different experiences together.
