However, if you win your case, the tribunal may reduce any pensation awarded to you as a result of your failure to appeal. Remember that in most cases you must make an application to an employment tribunal within three months of the date when the event you are plaining about happened. If your application is received after this time limit, the tribunal will not usually accept it. If you are worried about how the time limits apply to you, take advice from one of the anisations listed under Further help. Employment tribunals are less formal than some other courts, but it is still a legal process and you will need to give evidence under an oath or affirmation. Most people find making a claim to an employment tribunal challenging. If you are thinking about making a claim to an employment tribunal, you should get help straight away from one of the anisations listed under Further help. If you are being represented by a solicitor at the tribunal, they may ask you to sign an agreement where you pay their fee out of your pensation if you win the case. This is known as a damagesbased agreement. In England and Wales, your solicitor can39。 機械原理課程設(shè)計手冊 . 重慶:重慶大學(xué)出版社, 2022 [4]王知行 李瑰賢 . 機械原理電算程序設(shè)計 . 哈爾濱,哈爾濱工業(yè)大學(xué)出版社 .2022 [5] 孟憲源 姜琪 . 機構(gòu)構(gòu)型與應(yīng)用 . 北京:機械工業(yè)出版社, 2022 [6] 申永勝 . 機械原理教程 . 北京:清華大學(xué)出版社, 1999 [7 ] 陳明等 . 機械系統(tǒng)方案設(shè)計參考圖冊 g an employment tribunal claim Employment tribunals sort out disagreements between employers and employees.
