Acas offers free, impartial guidance on workplace rights and can explain whether early conciliation may be appropriate before an employment tribunal claim. You can also contact your trade union, if you have one, or Citizens Advice for practical support and information. Keep copies of relevant emails, payslips, contracts and notes of conversations, as employment tribunal time limits are often short—usually three months less one day. For advice about your particular circumstances, consider speaking to an employment solicitor regulated by the SRA.
