ACAS is a British public body that steps in when a company and its workers cannot agree about pay, hours, or how people are treated at work. It gives advice, helps both sides talk (conciliation), and can help settle the fight without a full court case. It is not a union and not the police; it is the official please-talk-this-out service in the UK. The letters stand for Advisory, Conciliation and Arbitration Service. People usually say it as a word, AY-kass, not letter by letter. You will see it in British news about strikes and workplace rights. Other countries have their own bodies; this name is the British one.
