Linear careers of the past, in which a worker stays in one job with one employer for most of their working life, are rapidly being replaced by the portfolio career. The portfolio career involves workers taking multiple projects, multiple roles, and consulting, as opposed to taking one single, full-time role. It's hard to say if portfolio careers are the wave of the future or a passing fad, but it is easy to understand the benefits. Portfolio careers allow individuals to diversify their income streams and offer the ability to balance their work around personal interests. Furthermore, employers benefit from the portfolio career by gaining access to top tier talent without having to shoulder the long term overhead. New technologies have also contributed to the rise of the portfolio career by offering solutions to logistical challenges like scheduling, and payments. The pandemic made these new practices commonplace, with more organizations being comfortable working with a portfolio of employees on a more temporary basis.
Regional Differences in Portfolio Career Adoption
While portfolio careers may be common in some European countries, portfolio careers as the new norm may not apply uniformly. Some EU countries have a relatively low proportion of the population that is self-employed, like Germany at 4%, but Greece and the surrounding countries like Poland and Czechia, and also countries that border other European countries like the Netherlands have a much higher proportion of the population that is self-employed, and thus arguably portfolio careers, at almost 18%, and roughly 12% and 12% respectively. Even more dramatic has been the change in Portugal, which has almost doubled its online freelancing over a five-year period to 46% of the workforce. The predominant profiles for freelancers are in software and other technology sectors.
Challenges and Risks of Portfolio Careers
While portfolio careers offer greater freedom in terms of job choice, they do not guarantee the same freedom in other career aspects. This means individual workers will need to address concerns related to financial security, health benefits and professional development. For approximately 2.1 billion workers (or around 58% of the world's workforce), informal work and employment are their only options, and more than 300 million live in conditions of extreme poverty. The ILO says that the current reality for more than half of all workers globally means they lack employment and are without security. While portfolio work may provide more options, there is no guarantee that those options won't mean greater income disparity. Some individuals may be able to demand higher wages due to their skills while other individuals will be forced to hold more jobs to make ends meet and will struggle to survive.
Government and Regulatory Responses
Governments have started taking actions, although these measures are sometimes not very clear. A directive from the EU on work performed via digital platforms in 2024 has led to more protection of workers by employment status presumptions and a requirement of algorithm transparency. As a result of this directive, around 28 million workers across Europe will be covered by these employment rights. Similarly, Spain introduced its "Riders' Law" in 2021 to clarify the delivery riders' status by categorizing them as employees. As in the previous example, Mexico also updated its labor law to define work performed on digital platforms as employment in cases that fall under certain salary requirements, with additional requirements for the employers on platforms of having an employment contract and other labor rights. This legislation is a significant advancement in employment protection in the context of the platform economy, and will certainly provide employment protections for many workers. With the "Platform Workers Act" in 2025, Singapore has introduced regulations that impose an employment obligation on platform operators in cases that meet the criteria of this act. As part of these regulations, platform operators must maintain comprehensive records and issue employment contract to the workers in scope. The new rules in Singapore will also make a contribution to the workers' retirement fund, and in this way, will provide protection and social security. These regulations should be understood as basic employment protections for a diverse and flexible category of employment.
The Core Issue: Benefits and Security Compared to Traditional Careers
What remains the true issue is whether the portfolio model will have the same benefits and potential security of the former career, such as the ability to anticipate and manage future needs, as well as developing and managing an identity. At this early stage of development, the portfolio model shows the benefits of an approach that prioritizes individuals in senior positions of responsibility and authority, such as those in the private practice of consulting, software, and creative positions. Those engaged in lower-paid, routine jobs, typically encounter greater service and schedule uncertainty and increased income volatility as a direct consequence of their work status, along with the traditional challenges of a lack of health insurance or retirement savings plans.
Conclusion: The Future of Employment as a Hybrid Landscape
What seems clear is that the single-employer career is no longer the default it once was, nor will it be again. The forces driving portfolio work—technological enablement, employer preference for flexibility, worker desire for autonomy, and the erosion of long-term job security—are structural, not cyclical. The future of employment is unlikely to be a pure portfolio economy or a return to permanent jobs, but a hybrid landscape in which some workers thrive on diversification while others require new forms of collective security. The policy challenge is to ensure that flexibility does not become a euphemism for abandonment, and that the portfolio career remains a choice rather than a sentence.
