2.—(1) A worker is a full-time worker for the purpose of these Regulations if he is paid wholly or in part by reference to the time he works and, having regard to the custom and practice of the employer in relation to workers employed by the worker’s employer under the same type of contract, is identifiable as a full-time worker.
(2) A worker is a part-time worker for the purpose of these Regulations if he is paid wholly or in part by reference to the time he works and, having regard to the custom and practice of the employer in relation to workers employed by the worker’s employer under the same type of contract, is not identifiable as a full-time worker.
(3) For the purposes of paragraphs (1), (2) and (4), the following shall be regarded as being employed under different types of contract—
(a)employees employed under a contract that is neither for a fixed term nor a contract of apprenticeship;
(b)employees employed under a contract for a fixed term that is not a contract of apprenticeship;
(c)employees employed under a contract of apprenticeship;
(d)workers who are neither employees nor employed under a contract for a fixed term;
(e)workers who are not employees but are employed under a contract for a fixed term;
(f)any other description of worker that it is reasonable for the employer to treat differently from other workers on the ground that workers of that description have a different type of contract.
(4) A full-time worker is a comparable full-time worker in relation to a part-time worker if, at the time when the treatment that is alleged to be less favourable to the part-time worker takes place—
(a)both workers are—
(i)employed by the same employer under the same type of contract, and
(ii)engaged in the same or broadly similar work having regard, where relevant, to whether they have a similar level of qualification, skills and experience; and
(b)the full-time worker works or is based at the same establishment as the part-time worker or, where there is no full-time worker working or based at that establishment who satisfies the requirements of sub-paragraph (a), works or is based at a different establishment and satisfies those requirements.
