The future of work is fractional
Where does the ideal balance lie between individual and organisational needs?
Organisations are hiring fractional expertise. Workers are building portfolio careers. Both claim this arrangement serves their interests. They’re both right, but that’s creating problems they don’t yet recognise.
The model promises efficient resource allocation for companies and autonomy for workers. What it delivers is a structural mismatch between how organisations build capability and how humans develop expertise.
Fractional work is often the gateway to portfolio diversification for individuals. Why depend on one employer when you can spread risk across five clients?
Great in theory, but a 2024 Stanford study tracking 200 fractional workers over two years found that 73% underestimated the switching costs of serving multiple clients simultaneously. Changing contexts (tools, cultures, strategic priorities, communication styles) so often increases cognitive load and reduces the opportunity for deep engagement that offers job satisfaction.
From an organisational perspective, MIT’s 2023 study of 400 companies using fractional executives found that strategic initiatives led by fractional leaders were 60% less likely to be implemented than those led by full-time executives. This is because implementation requires organisational context that takes time to build.
The fractional CMO might be brilliant, but she doesn’t know that the sales team ignores marketing leads, that the CEO hates the brand colours, or that the last three marketing initiatives failed because of an unspoken turf war with product. This institutional knowledge can’t be efficiently transferred. It accumulates through presence.
The hidden problem: cohesion
Fractional work systematically degrades “cohesion” - the objective level of understanding between component parts of a team system.
Gainline Analytics’ research, validated over time across professional sports like rugby, football and cricket shows cohesion can account for 30-40% of team performance variation. When their founders analysed corporate teams using the same framework, they’ve found stock market returns correlated strongly with these cohesion metrics.
Their research is brutal; it suggests cohesion grows slowly through repeated interaction, but you can destroy it really quickly.
If a fractional exec cycles through a key role every 18 months, the organisation doesn’t just lose their expertise, it destroys the accumulated understanding between marketing, sales, product, and leadership that took months to build.
“In a high-cohesion environment, everyone is performing to capacity. If you are a low cohesion team, it doesn’t matter what the quality of the new player is, they won’t look very good.”
Organisations hiring brilliant fractional executives who underperform aren’t necessarily hiring the wrong people, they’re just operating in environments where cohesion levels prevent anyone from performing to capacity.
Where the tension lies
Organisations need embedded expertise that builds cohesion and accumulates institutional knowledge. Talented individuals want portfolio diversification that reduces their dependence on any single employer. Both are rational responses to genuine problems: corporate layoffs justify worker scepticism about loyalty; market volatility justifies corporate scepticism about fixed overhead.
But pursuing them simultaneously creates a system where organisations can’t grow their capability, teams fail to build cohesion and workers stop developing deep expertise.
So when does fractional work?
The model succeeds in specific, bounded conditions:
Discrete projects with clear endpoints. A 2024 study of 300 design projects found fractional arrangements completed on time 15% more often than full-time equivalents for projects under six months, but 40% less often for ongoing strategic work. Fixed term work doesn’t demand high organisational cohesion.
Genuine specialisation used rarely. Examples include fractional legal counsel for patent filings, fractional security auditors for compliance reviews; these work because organisations genuinely need the expertise infrequently, and low interaction frequency doesn’t demand sustained cohesion.
Strong documentation systems. Organisations that make fractional arrangements work invest heavily in knowledge management infrastructure. These systems can be expensive (often costing more than just hiring someone full-time) but without them, the fractional model degrades organisational capability over time.
The unresolved choice
Future of work literature treats fractional arrangements as progress toward better labour markets. But markets don’t move toward “better”, they move toward whatever fits current conditions.
If those conditions include platforms that make fractional coordination easier, corporate cultures that resist long-term commitment, and workers who’ve learned that loyalty doesn’t protect them, then fractional work will proliferate regardless of whether it builds organisational capability, cohesive teams or deep individual expertise.
The ideal balance question assumes someone is optimising the system. But labour markets emerge from millions of individual decisions that can produce collectively suboptimal outcomes. The fractional model might be simultaneously rational for each participant and destructive for the system as a whole.
What we know from organisational research is that capability compounds over time through embedded expertise and cohesion. What we know from labour economics is that workers bearing all employment risk will diversify to protect themselves. These two truths point in opposite directions.
The balance we’re looking for might not exist. What does is a choice about which kind of fragility we’re willing to accept: organisational fragility from lack of cohesion and institutional memory, or individual fragility from employment dependence.
The evidence doesn’t tell us which to choose. It just shows us that we can’t avoid choosing.
I'm building a portfolio career whilst writing about its structural problems. That irony isn't lost on me. But understanding the trade-offs - what you gain in autonomy, you sacrifice in cohesion and depth - matters more than pretending there's a 'right' way to navigate this. The research shows these costs are structural, not planning failures. You can be intentional about which fragility you accept, but you can’t optimise your way out of the fundamental tension. For the past few years I’ve chosen autonomy over depth, and know first hand what that costs.
My personal reflection is that many of us think we can build portfolio careers like investors curate diversified portfolios - blue chip fractional roles for stability, equity compensation for the upside potential, creative content assets.
The last one is the only path that offers both autonomy and depth: valuable assets that compound independently of trading time for money.
Cal, really like this framing around cohesion/institutional knowledge.
One benefit I’d add to the “when does fractional work?” list: outsider perspective. When you’re deeply inside a culture, you stop seeing the contradictions and weak links that are hiding in plain sight. A good fractional leader can break groupthink and surface the real constraints fast.
Also, there’s a courage angle: fractional folks might have more room to give candid feedback because they’re not as exposed to the “say the wrong thing and it shows up in your performance review” dynamic. That candor can lead to breakthroughs - if the org is mature enough to receive it.
I tried marketing myself as a fractional marketer but found this market sector quite challenging, and pivoted to portfolio that includes other things besides fractional work.
The dynamics of fractional will keep this opportunity quite limited:
-Most fractionals are senior experienced people, either laid off or tired of corporate, but the opportunities don’t pay well because most have small budgets. Many fractionals struggle to match their previous job salary.
-Large corporations don’t hire fractionals as to your article’s point they have embedded full time leaders. So most fractional opportunities seem to be for startups and SMBs who often cannot afford your senior level rate.
-Once you’ve reached VP or C suite level you are not wanting to do hands on work, which is what startups and SMBs need. Often there is little or no staff to manage. So it’s less strategic than advertised, and often essentially turns into consulting or freelancing.
-Fractional work is better for sharply defined things as you described. Fractional CFOs seem a better fit than CMO or CTO or COO type roles. Some people think any role can be fractionalized but I think some are not well suited to this at all.
-There is quite intense competition. The limited number of fractional exec roles far outweighs the people vying for these roles, and you find yourself competing against highly qualified people who’ve also been a VP/C suite etc.
-Thus it feels like a red ocean to me, many people fighting for few roles that result in downward price pressure/race to the bottom.
Not for me any more.
