How can I challenge an unfair dismissal in the UK?

Check your eligibility: Ensure you’ve been employed for at least 2 years (or 1 year if hired before April 2012) to file an unfair dismissal claim.
Contact ACAS: Start the Early Conciliation process through the Advisory, Conciliation and Arbitration Service (ACAS).
File a tribunal claim: If conciliation fails, submit your claim to the Employment Tribunal within 3 months less one day from your dismissal date.
Gather evidence: Include contracts, emails, or witness statements that support your case.
Seek legal advice: Consult a solicitor to improve your chances of a successful claim.
You can find more information on filing a claim on the Employment Tribunal website.
