151. Where the arbitrator finds that the Employee has unreasonably refused an offer by the Employer which (if accepted) would have the effect of reinstating the Employee in his or her employment in all respects as if he or she had not been dismissed, the arbitrator shall reduce or further reduce the basic amount to such extent as he or she considers just and equitable having regard to that finding.
152. Where the arbitrator considers that any conduct of the Employee before the dismissal (or, where the dismissal was with notice, before the notice was given) was such that it would be just and equitable to reduce or further reduce the basic amount to any extent, the arbitrator shall reduce or further reduce that amount accordingly. In assessing such conduct, the arbitrator shall disregard (if relevant) those matters set out in section 155 of the Trade Union and Labour Relations (Consolidation) Act 1992, as amended from time to time.
153. The preceding paragraph does not apply in a redundancy case (see paragraph 150(i) above) unless the reason for selecting the Employee for dismissal was one of those specified in paragraph 147 above (“Minimum basic amounts in certain cases”), and in such a case, the preceding paragraph applies only to so much of the basic amount as is payable because of paragraph 147 above.
154. Where the Employee has been awarded any amount in respect of the dismissal under a dismissal procedures agreement designated under section 110 of the Employment Rights Act 1996 (as amended from time to time), the arbitrator shall reduce or further reduce the amount of the basic award to such extent as he or she considers just and equitable having regard to that award.
155. The basic amount shall be reduced or further reduced by the amount of any payment made by the Employer to the Employee on the ground that the dismissal was by reason of redundancy (whether in pursuance of Part XI of the Employment Rights Act 1996, as amended from time to time, or otherwise).
