Working out whether someone is an employee is a question about reality

A label is a claim, not a conclusion

Contracts describing someone as self-employed, as a consultant, or as an independent supplier are extremely common, and in most legal systems the description is a starting point rather than an answer. Decision-makers look at what the parties actually do, and where the label and the reality diverge, the reality usually wins.

The reasoning is straightforward once stated. If a label were decisive, the protections attached to employment could be removed from anybody simply by writing a different word at the top of the page. Systems that regard those protections as worth having therefore treat status as a question of substance, whatever the parties called it.

What decision-makers tend to look at

The tests differ by jurisdiction, but a recognisable cluster of factors recurs. Who controls what work is done, when, where and how. Whether the person must perform the work personally, or may send a substitute. Whether the arrangement carries genuine financial risk and the chance of profit from managing it well. Whether the person is integrated into the organisation or supplies a service to it from outside.

No single factor is usually decisive, which is what makes status arguments so unpredictable. It is a weighing exercise, and two arrangements that look similar on paper can fall on different sides of the line because of how one detail operates in practice. That unpredictability is worth taking seriously before building a business model on an assumption about it.

Control and substitution do most of the work

Control is the oldest of the factors and still among the most influential. A person told what to do, how to do it, and when to be somewhere looks like an employee, regardless of what they invoice. A person engaged to achieve an outcome, using their own methods and their own judgement about scheduling, looks less like one.

Substitution is the sharpest test in several systems. If the arrangement genuinely permits sending someone else to do the work, the relationship is much harder to characterise as employment, because employment is ordinarily personal. But the right has to be real. A clause permitting substitution that nobody could actually use, or that requires approval always withheld, tends to be given little weight.

Why the answer matters so much

Status is not a technicality; it is the gateway. In most systems the substantial protections — around dismissal, notice, leave, sick arrangements, discrimination in some contexts, and collective rights — attach to employment or to a defined category of worker. Someone genuinely running their own business generally has the protections of contract law and little else.

It also determines tax and social security treatment, and here is a trap worth naming: the answer for tax purposes and the answer for employment rights are not always the same, even within one country. A person can be treated as self-employed by one authority and as an employee by another, because the tests were written for different purposes.

The categories in between

Several jurisdictions have created intermediate statuses for people who are neither straightforwardly employed nor genuinely in business on their own account — dependent contractors, workers, and similar categories carrying some rights but not all. These exist because the binary was producing results that satisfied nobody.

Platform and gig arrangements have pushed hard on all of this, and the position is genuinely unsettled in many places. Legislatures and courts in different countries have reached different conclusions on similar facts, and some of those conclusions have since changed. Anyone told that the position is now settled should ask settled where, and as of when.

Mutuality of obligation is the further factor that recurs, and it is the hardest to state briefly. It asks whether each side owes the other anything between assignments — whether work must be offered and must be accepted — and where nothing is owed in the gaps, the relationship looks less like continuous employment. Arrangements built from a series of separate engagements often turn on this point, and the answer can differ depending on whether you examine a single engagement or the pattern across several years.

How to get an answer that is worth having

Because status is fact-sensitive and locally defined, a general article can describe the factors but cannot apply them. The same arrangement really can produce different answers in two neighbouring jurisdictions, and the answer can change over the life of a relationship as the working pattern drifts.

If status matters to you — because a relationship has ended, because a tax position is being challenged, or because you are structuring engagements — the right route is a qualified lawyer or a specialist adviser in your own jurisdiction. Do it promptly. Claims that depend on status are often subject to short time limits, and arguing about status after the deadline has passed is an expensive way to be right.
