You may need to make a claim to an employment tribunal if: ? you don39。t appealed against the disciplinary action your employer has taken against you. However, if you win your case, the tribunal may reduce any pensation awarded to you as a result of your failure to appeal.

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. 華東交通大學(xué)理工學(xué)院課程設(shè)計(jì)報(bào)告 第 頁 共 32 頁 30 Most people find making a claim to an employment tribunal challenging.

It might be best to get advice from an experienced adviser, for example, at a Citizens Advice Bureau. To find your nearest CAB, including those that
