"mutuality of obligation and the requirement of control on the part of the potential employer are the irreducible minimum for the existence of a contract of employment: see Nethermere (St Neots) Ltd -v- Gardiner[1984] IRLR 240 , 245 per Stephenson LJ, approved in Carmichael -v- National Power plc[2000] IRLR 43 , 45 per Lord Irvine of Lairg LC."
"I must now consider what is meant by a contract of service. A contract of service exists if these three conditions are fulfilled. (i) the servant agrees that, in consideration of a wage or other remuneration, he will provide his own work and skill in the performance of some service for his master. (ii) He agrees, expressly or impliedly, that in the performance of that service he will be subject to the other's control in a sufficient degree to make that other master. (iii) The other provisions of the contract are consistent with its being a contract of service."
"It is important to look at the issues of mutuality of obligation and the question of control of the Applicant, while taking account of all other factors that one would normally expect to see in a relationship of employer and employee. In this case it is clear that the day to day control of the Applicant's work lay with her manager, who is an employee of the Respondent, but the Tribunal is of the view that day to day control is not in itself sufficient as that would normally rest with the company where the worker actually worked, rather than an employment agency, because there is not normally any practical alternative. That would even be the case if an agency placed a worker with a company for just a single day. The Tribunal's view is that it is important to look further and to see if there are any additional factors indicating an employer and employee relationship exists and, in particular, that a mutuality of obligation has arisen. In this case it is noted that the Applicant had been providing services for the Respondent for a long period of time similar to the workers in the cases of Motorola and Montgomery. However, unlike both those cases, the Applicant had not been placed long-term in one role that was in practice for an indefinite period, but had been placed in various roles on a series of fixed-term contracts, which is less consistent with employment by the company where she is placed. BPS also continued to exercise significant areas of control. They paid the salary and any sick or holiday pay entitlement and set out detailed conditions of employment, including grievance and disciplinary procedures. This is very different to the situation in Motorola where the facts showed that the worker was in almost every respect treated the same as any other permanent employee with, for example, Motorola using their disciplinary procedure to deal with the worker. So, given the specific facts of this case, the Tribunal is satisfied that the Applicant did not at any stage become an employee of the Respondent, as there was an absence of mutuality of obligation and as significant areas of control of the Applicant remained with BPS. As the Applicant was not an employee of the Respondent, her claims must be dismissed."
"Nor, further as we see it, does one necessarily disprove the existence of a degree of control over a worker consistent with his being an employee of A by showing that B had equal or even greater powers over him."
