"Free of authority, we understand the statutory framework ... involve a three-stage process:
"(1) There may be a number of underlying causes leading to a true redundancy situation; our stage 2. There may be a need for economies; a reorganisation in the interests of efficiency; a reduction in production requirements; unilateral changes in the employees' terms and conditions of employment. None of these factors are themselves determinative of the stage 2 question. The only question to be asked is was there a diminution/cessation in the employer's requirement for employees to carry out work of a particular kind, or an expectation of such cessation/diminution in the future [redundancy]? At this stage it is irrelevant to consider the terms of the employee's contract of employment. That will only be relevant, if at all, at stage 3 (assuming there is a dismissal).

So an employee is redundant as defined when he is dismissed because his particular specialism is no longer required, even if he is replaced by an employee with a different specialism so that, overall, the requirements of the business for employees have not ceased or diminished."
"The statute enquires what are the requirements of the business for employees to do work of a particular kind. The personal attributes of the employee are not therefore relevant except in so far as they reflect upon his ability to perform the relevant tasks."

We decide that there are different levels of producer depending on experience and ability, in the same way that there are different levels of teachers, and that the [ BBC ] need a varied range.
