Conciliation

In the employment context, conciliation is not just a voluntary courtesy service but a compulsory gateway to litigation: Acas states that early conciliation "is a legal process" and that a prospective claimant "must notify Acas" of an intended employment tribunal claim before the claim can be lodged. Once notified, Acas "will then offer early conciliation", during which "an Acas conciliator tries to help you reach a legal agreement with your employer" so as to avoid a tribunal hearing altogether. Although notification is mandatory, taking part in the conciliation itself is not: Acas is explicit that "early conciliation is voluntary" and that "you and your employer can choose whether to take part."

The process runs to a statutory clock: Acas guidance confirms that "early conciliation can last up to 12 weeks", after which, if no settlement is reached, Acas issues an early conciliation certificate bearing a reference number the claimant must enter on the ET1 tribunal claim form. Acas warns claimants that "if we do not hear back from you, we'll send you the certificate you need to take to an employment tribunal", and that once the certificate is issued the claimant will normally "have at least 1 month from the date you received the certificate to make your claim" - the early conciliation period itself being deducted from the running of the normal tribunal time limit. This mechanism is what distinguishes statutory conciliation from purely private mediation: it is woven directly into the procedural timetable for bringing a claim, not merely an optional add-on.
