Under the now repealed statutory dispute resolution procedure an employment tribunal had/has no jurisdiction to consider claims by an employee which concern matters the employee did not raise with the employer in a written grievance prior to the commencement of Tribunal proceedings. Nor could/can parties other than the claimant's employer be, or be added as, respondents to the Tribunal proceedings unless they had been named in a grievance letter written 28 days before proceedings began as responsible for the matters complained of.
