"'BANK' THEATRE PORTER DUTIES This letter acknowledges your written enquiry as to any interest I may have in an offer of permanent employment on an annual hours basis, and confirms that I have declined to take it up. Instead I would prefer to offer you my services as an independent contractor. I hereby offer you my services as a 'Bank' theatre porter, available to work with your theatre staff on an 'as and when' basis. My fees will be£4.40 per hour (variable and reviewed annually). I will be an independent contractor and you will pay me monthly, in arrears, with deductions for tax and national insurance (as required by the Inland Revenue). I understand that I have the right to refuse the offer of work if it is inconvenient to me and that the Hospital reserves the right to cancel advance bookings if circumstances are such that additional help is not required. Whilst I am not required to be available to work, and whilst you are unable to guarantee that you will provide work for me, I do recognise that if I am unable to offer myself for work within four consecutive weeks then my name will be removed from the Bank List. I also acknowledge that if I cancel your booking on four consecutive occasions my name will be removed from the Bank List. I also appreciate that occasions of sickness or holidays cannot be charged for."

"With respect to the Claimant the main flaw in that argument is that, as he himself agreed, he didn't have to accept the hours and duties allocated to him, but chose to do so; and that he had a choice of whether or not and when to work for the Respondent. Whilst the exercise of that choice might well not endear him to the Respondent, and might very well have led to an early termination of the working relationship between him and the Respondent (as in fact provided for in some of the letters the Claimant signed), the very existence of such a choice or option is inconsistent with his claimed status as an employee, and in particular with the existence of a mutuality of obligations between the parties, respectively to undertake and to provide work. As a further example of this principle, the Respondent could, and occasionally did, send home "
"11. The significance of mutuality is that it determines whether there is a contract in existence at all. The significance of control is that it determines whether, if there is a contract in place, it can properly be classified as a contract of service, rather than some other kind of contract." and at paragraph 13: "13. The question of mutuality of obligation, however, poses no difficulties during the period when the individual is actually working. For the period of such employment a contract must, in our view, clearly exist. For that duration the individual clearly undertakes to work and the employer in turn undertakes to pay for the work done. This is so, even if the contract is terminable on either side at will. Unless and until the power to terminate is exercised, these mutual obligations (to work on the one hand and to be paid on the other) will continue to exist and will provide the fundamental mutual obligations."
"The important point is that, once a contract was entered into and while the contract continued, she (the Claimant) was under an obligation to teach the pupil and the Council was under an obligation to pay her for teaching the pupil made available to her by the Council under that Contract. That was all that was legally necessary to support the finding that each individual teaching engagement was a contract of service."
