"17 We were referred to no authority giving guidance on that question; and we accordingly spell out our approach to it in a little detail, as follows: (1) We focus on the terms '[carrying on a] business undertaking' and 'customer' rather than '[carrying on a] profession' or 'client'. Plainly the applicants do not carry on a 'profession' in the ordinary sense of the word; nor are Byrne Brothers their 'clients'. (2) '[Carrying on a] business undertaking' is plainly capable of having a very wide meaning. In one sense every 'self-employed' person carries on a business. But the term cannot be intended to have so wide a meaning here, because if it did the exception would wholly swallow up the substantive provision and limb (b) would be no wider than limb (a). The intention behind the regulation is plainly to create an intermediate class of protected worker, who is on the one hand not an employee but on the other hand cannot in some narrower sense be regarded as car rying on a business. (Possibly this explains the use of the rather odd formulation 'business undertaking' rather than 'business' tout court; but if so, the hint from the draftsman is distinctly subtle.) It is sometimes said that the effect of the exception is that the Regulations do not extend to 'the genuinely self-employed'; but that is not a particularly helpful formulation since it is unclear how 'genuine' self -employment is to be defined. (3) The remaining wording of limb (b) gives no real help on what are the criteria for carrying on a business undertaking in the sense intended by the Regulations - given that they cannot be the same as the criteria for distin guishing employment from self-employment. Possibly the term 'customer' gives some slight indication of an arm's length commercial relationship - see below - but it is not clear whether it was deliberately chosen as a key word in the definition or simply as a neutral term to denote the other party to a contract with a business undertaking. (4) It seems to us that the best guidance is to be found by considering the policy behind the inclusion of limb (b). That can only have been to extend the benefits of protec tion to workers who are in the same need of that type of protection as employees stricto sensu - workers, that is, who are viewed as liable, whatever their formal employ ment status, to be required to work excessive hours (or, in the cases ofPart II of the Employment Rights Act 1996 or theNational Minimum Wage Act 1998 , to suffer unlawful deductions from their earnings or to be paid too little). The reason why employees are thought to need such protection is that they are in a subordinate and dependent position vis-à-vis their employers: the purpose of the Regulations is to extend protection to workers who are, substantively and economically, in the same position. Thus the essence of the intended distinction must be between, on the one hand, workers whose degree of dependence is essentially the same as that of employees and, on the other, contrac tors who have a sufficiently arm's-length and independent position to be treated as being able to look after them selves in the relevant respects. (5) Drawing that distinction in any particular case will involve all or most of the same considerations as arise in drawing the distinction between a contract of service and a contract for services - but with the boundary pushed fur ther in the putative worker's favour. It may, for example, be relevant to assess the degree of control exercised by the putative employer, the exclusivity of the engagement and its typical duration, the method of payment, what equip ment the putative worker supplies, the level of risk under taken etc. The basic effect of limb (b) is, so to speak, to lower the pass-mark, so that cases which failed to reach the mark necessary to qualify for protection as employees might nevertheless do so as workers. (6) What we are concerned with is the rights and oblig ations of the parties under the contract -not, as such, with what happened in practice. But what happened in practice may shed light on the contractual position: see Carmichael (above), esp. per Lord Hoffmann at pp.1234-1235. (7) We should add for completeness that, although the Regulations are of course based on the Working Time Directive, we were referred to no provision of the Directive nor any case law of the ECJ. which sheds any light on the present issue. The Directive does not contain any defini tion of the term 'worker'."
"Briefly put, it is argued that a distinction should be maintained between two related, but separate, characteristics of employment relationships: dependency and democratic deficits (often referred to, in this context, as subordination). While 'employees' should be identified by the accumulation of both characteristics, the group of 'workers' should consist of people who are dependent (mostly eco nomically) on the relationship with a particular employer, even when no demo cratic deficits exist. Otherwise put, it is argued that 'workers' should not be identified as being 'semi-dependent', as has been suggested. Rather, this inter mediate category should catch work relationships that are characterised by significant dependency on a single employer, even when no subordination exists."
"5. This distinction fits perfectly with the definition of 'worker' under UK legislation. As mentioned above, the three pillars of the definition are the contractual rela tionship, the personal nature of the engagement and the lack of an independent business undertaking. The last requirement can and should be understood as dependency on a particular client-employer. It is not the formalities of having a 'business' for tax or other purposes that matter, but the extent to which this 'business' is truly independent. If you only work vis-à-vis one specific client and depend on it, there is no reason why this client-employer should not be obliged to pay minimum wage or observe working time regulations. And the 'worker' definition appears to recognise that. Hence, the main question when examining whether one is a 'worker' or not should be to what degree is this person independent - not in the sense of controlling her own time and making her own decisions (which is relevant for inclusion within the group of the better-protected 'employees') - but in the sense of being able to spread her risks among a number of different relationships.16 Dependency on a specific relationship - especially economic dependency, but also dependency for the fulfilment of social and psychological needs-justifies various kinds of reg ulatory protections. Suffering in addition from democratic deficits (subordination) justifies the application of a broader range of regulatory protections. This, in my view, is the most useful way to differentiate between 'workers' and 'employees'."
