Being dismissed, or managed briskly towards the exit, comes with a clock attached. Employment tribunal deadlines are short, commonly three months less a day from the dismissal or the act you are complaining about, and they are applied strictly. Before you think about lawyers at all, work out your date and write it somewhere you will see it.
You cannot normally start a tribunal claim without first notifying ACAS, the conciliation service, and going through its early conciliation process. This is free, it pauses the limitation clock while it runs, and a decent share of disputes settle during it without anyone drafting a claim. The ACAS helpline will also explain your rights over the phone at no cost, which makes it the right first call for most people even when they suspect the dispute will go further. Talking to ACAS commits you to nothing except a pause and a conversation.
Some situations put a lawyer in the room whether you planned it or not. A settlement agreement, the document employers use to pay for a clean break, only binds you if you have had independent advice on it, and the employer normally contributes towards the cost of that advice. Beyond settlement agreements, the cases where paying for representation tends to earn its keep are the heavier ones: discrimination and whistleblowing claims, where the law is intricate and compensation is not capped, and senior exits involving notice pay, bonuses, share schemes or restrictive covenants, where the contract is doing most of the work.
Funding deserves a blunt conversation at the first contact. Legal aid is rarely available for employment matters. Some employment solicitors will act on no-win-no-fee terms for strong claims, taking their fee as a share of any award, and it is worth asking whether your household or motor insurance includes legal expenses cover, a benefit many people carry without knowing it exists.
Your contract and the staff handbook. The dismissal letter or the emails that show what happened, in date order. A short written timeline with names and dates. Your payslips, because losses have to be calculated from something. A solicitor who receives this bundle can tell you in one conversation whether the claim looks worth pursuing; a solicitor who receives a phone call and a strong sense of grievance cannot.
The order of operations for most people is this: note the deadline, ring ACAS, gather the paperwork, and bring in a solicitor at the point where money is on the table or the claim is complex. This site lists 2,926 solicitors' firms and shows which of them handle employment work for individuals. Find employment solicitors near you, or set out the situation once and let firms come back with what they would charge. And whatever else happens this week, check the date. Everything in this area of law bends around it.
