For more informu, take advice from one of the anisations listed under Fur ther 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. ation about dismissal and unfair dismissal, see Dismissal.

When the sadness strikes, take a deep breath and lean into it. When we run away from sadness that’s unfolding in our lives, it gets stronger and more real. We take an emotion that’s fleeting and make it a solid event, instead of something that passes through ，別再逃跑或隱藏痛苦，試著擁抱它吧；當悲傷來襲時，試著深呼吸，然后直面它。t really grow up, it seems is not so important。t appealed against the disciplinary action your employer has taken against you.
