Acas is seeking views on a specific change to the code relating to the legal right workers have to be accompanied at a disciplinary or grievance hearing.
This change comes as a result of an employment appeal tribunal hearing earlier this year, which suggested that the code did not accurately reflect the law on the statutory right of accompaniment at disciplinary or grievance hearings.
Acas council chair Ed Sweeney said: "We recognise that the current wording does not accurately interpret the law, which is why we have decided to amend the code.
"Although comments are not being sought on the code as a whole at this point in time, we will continue to keep it under review."
