A courier picks up an order in central Athens. The app assigns the run, calculates the payout, tracks the route, and ranks the courier against peers competing for the next high-demand slot. On paper, that courier is self-employed. In practice, most of the substantive parameters of the working day are set by the platform, not the person on the bike.

EU Directive 2024/2831 is designed to close that gap. As Efimerida ton Syntakton reported, the directive seeks to draw clearer boundaries between genuine self-employment and dependent work for platform workers, and it introduces a legal presumption of salaried employment when real-world data shows elements of direction and control. The mechanism that matters most sits underneath: the burden of proof shifts. Platforms will need to demonstrate that a self-employed collaborator has genuine professional autonomy, rather than a courier having to prove they are effectively salaried.

That is the shift in theory. In Greek delivery, enforcement will run into a very specific obstacle: the country's invisible courier workforce, people working through accounts registered under someone else's name. If the regulator cannot reach them, the presumption cannot protect them.

What the directive actually changes

The EU intervention is targeted at what regulators call false self-employment: someone appears contractually as an independent contractor, but the platform effectively determines how, when, and for how much they work. That framing matters because it moves the argument away from job titles and towards observable facts.

Two mechanisms do the work. The first is the presumption of employment: when data shows direction and control, the labour relationship is treated as salaried by default. The second is algorithmic transparency. Platforms will be required to inform workers about the use of automated systems and guarantee human intervention plus the possibility to review important decisions. Choices with critical consequences, for example deactivation, income cuts, or exclusion from peak hours, cannot be left solely to an algorithm.

This is a live issue in delivery precisely because the platform's algorithm is the workplace. It can influence order assignment, courier evaluation and ranking, access to high-demand hours, and ultimately worker income. Once those decisions have to be explained and reviewable by a human, the legal picture of who is really the employer starts to look different.

Greece already has a framework. That is the complication.

Greece is not starting from zero. Under Law 4808/2021, there is already a presumption of independent service provision when specific autonomy conditions are met: the courier chooses their working time, can reject tasks, and can collaborate with other platforms. On paper, that framework is coherent. The directive now pushes in the opposite direction, asking whether those autonomy markers are real or contractual boilerplate.

The interesting question for Greek regulators is not whether the two frameworks conflict, they can be reconciled, but which one describes the daily reality of a courier in Athens or Thessaloniki. If a rider cannot realistically reject orders without ranking penalties, or cannot collaborate with a competitor without losing access to profitable hours, the choice conditions of the 2021 law start to look thin. That is exactly the kind of real-world evidence the directive is designed to weigh.

The invisible workforce problem

Here is where enforcement gets hard. A significant share of Greek couriers work through accounts registered under someone else's name. The person on the bike is not the person on the platform's records. That leaves the actual worker outside insurance coverage and outside labour protection, regardless of what any directive says.

A presumption of employment is powerful only when the regulator knows who the worker is. If the account holder is a friend, relative, or a third party running several accounts as an informal sub-contract, the directive's protections stop at the login screen. Fixing that is less a legal problem than an identification problem, and it will determine whether the directive delivers real coverage or a headline reform.

For couriers: what you should watch for

If you deliver for a platform in Greece under your own account, the directive changes what you can ask for and what the platform has to disclose.

• Algorithmic transparency. You should be informed when an automated system is being used to assign orders, rank you, or restrict access to hours. Ask what data feeds the decision.
• Human review of consequential decisions. If your account is deactivated, downgraded, or excluded from peak slots, you should have a route to a human review, not just an appeal button that loops back to the same algorithm.
• Real autonomy, not contractual autonomy. If your contract says you can reject tasks or work for competitors but doing either costs you rankings and income, that is evidence relevant to whether you are genuinely self-employed.

If you work through someone else's account, the directive does not reach you directly. The route into coverage still runs through registering as the actual worker, which is uncomfortable but is the only path the presumption can protect.

For HR and platform operators: compliance is now an evidence exercise

If your organisation contracts delivery couriers or any platform-mediated workforce in Greece, the practical shift is that classification is no longer a contract-drafting problem. It is an evidence problem.

Three areas need attention:

• Algorithmic decision inventory. Map every automated decision that affects a worker's income, hours, ranking, or access. Each one now needs a documented human-review path and a plain-language disclosure to the worker.
• Autonomy evidence. The Law 4808/2021 autonomy markers, time choice, task rejection, multi-platform collaboration, need to hold up as observable behaviour, not just contractual clauses. If the data shows couriers who reject tasks lose ranking, expect that to weigh against the self-employment classification under the new burden of proof.
• Account-integrity controls. Invisible workers are a compliance risk for platforms as much as a protection gap for workers. Identity verification at onboarding and periodic re-verification reduce the exposure that comes from a workforce whose real identity the platform does not know.

Reclassification cost is the tail risk. If a Greek labour inspector, or a court, applies the presumption to a cohort of couriers and the platform cannot produce evidence of genuine autonomy, the exposure includes back-dated social contributions, insurance, and potential penalties. The compliance work now is cheaper than the reclassification bill later.

What to watch next

The directive sets the rules. The real test is how Greek authorities integrate it with Law 4808/2021 and, harder, how they identify the couriers the current system does not see. A presumption of employment that reaches only the visible workforce would formalise a two-tier delivery labour market: registered couriers on the protected side, invisible ones on the other. Whether the directive avoids that outcome is the enforcement question worth watching over the next year.
