If your employer dismisses you they must have a fair reason for their action, eg because of your conduct at work. Find out more about what fair reasons for dismissal are, and what your employment rights are if you are dismissed.
If your employer has dismissed you because of your conduct, it usually means you have broken one or more of the terms of your employment. For example:
Your employer should follow a fair disciplinary procedure before dismissing you for misconduct.
If your employer has dismissed you for your capability it may mean that you aren’t performing to the required standard or that you can't do your job properly, including because you don't have the right qualifications. For example:
Your employer should make sure you are given adequate training to do your job. If you're performing poorly, you should usually be warned that your work isn't satisfactory and given a chance to improve before any action is taken.
If you are persistently off sick (or on long-term sick), your employer should normally look at any alternatives before deciding to dismiss you. For example, they might have to consider whether the job itself is making you sick and needs to be changed.
You can still be dismissed if you are off sick.
Your employer would normally be expected to allow a reasonable amount of time for you to recover from your illness. The actual amount will depend on things like:
If you have a disability (which may include long-term illness), your employer has a legal duty to try to find a way round the problem. They must make 'reasonable adjustments' to how and/or where you work. Dismissal because of a disability may be unlawful discrimination.
Redundancy is a type of dismissal. Redundancies take place when there is no longer enough (or any) work for an employee at a company. If you are being made redundant then your employer has several responsibilities towards you to make sure you are dismissed fairly.
If your employment contract ends because you are retiring this is a type of dismissal. In order for retirement to be a fair dismissal your employer must follow the legal retirement procedure. This means you must have at least six months' notice of retirement. If you want to continue working past retirement then your employer must consider your application.
If your employment has ended or will end before the retirement age set out in your employment contract, it cannot be classed as retirement.
Your employer can dismiss you if continuing to employ you would break the law - for example, if you are a driver and you lose your driving licence. Your employer would be expected to try to find other suitable work for you before choosing to dismiss you.
The emphasis here is on 'substantial'. 'Another substantial reason' applies to a situation where your employer has an overwhelming reason why you must be dismissed. They would be expected to look at any alternatives before choosing to dismiss you. Reasons that have previously fallen into this category include:
