"(1) Where an employer is proposing to dismiss as redundant 20 or more employees at one establishment within a period of 90 days or less, the employer shall consult about the dismissals all the persons who are appropriate representatives of any of the employees who may be so dismissed.
"(1) Where an employer has failed to comply with any requirement of section 188, a complaint may be presented to an industrial tribunal on that ground - (a) in the case of a failure relating to employee representatives, by any of the employee representatives to whom the failure related, (b) in the case of a failure relating to representatives of a trade union, by the trade union.
"(1) In this Chapter references to dismissal as redundant are references to dismissal for a reason not related to the individual concerned or for a number of reasons all of which are not so related.
"16. Doing our best with the evidence which we have read and heard, we have come to the conclusion that there was a policy, albeit unstated in writing, that managers would apply the selection criteria to their sales representatives and sales managers. Those who failed to meet the criteria would be invited to take the early retirement package. Those who resisted appear to have become isolated so that they had little option but to accept. The existence of the selection criteria and the absence of any written assurance that sales representatives could continue under the old regime indefinitely supports our view that the respondent aimed to have the new structure in place by the end of the year and set about in the meanwhile removing those who either were unwilling or unable to conform to the new requirement both of structure and of conformity to the regulatory regime. Those individuals were given the option in effect of either going or becoming isolated. If they were offered agency status, they had the option of either accepting it or going. In any event the respondent intended unilaterally to impose new terms and conditions upon those employees. In so far as employees were unwilling to accept and felt obliged to go, the respondent was committing a fundamental breach of contract. Those who went were, on the evidence which we have seen in this case, constructively dismissed."
"17. It follows, therefore, that the respondent did at the outset propose to dismiss as redundant employees of a description in respect of which the applicant was recognised by it. ..."
