Negotiating union recognition rules define membership verification, secret ballot procedure, employer facilities, and tribunal access for trade union disputes. Negotiating union or negotiating council may negotiate with the employer on matters including wages, working hours, leave, promotion, safety, service conditions, and other agreed issues. A single registered Trade Union with at least thirty per cent membership must be recognised as the sole negotiating union, while other cases require membership verification by an appointed verification officer through records scrutiny and, where necessary, secret ballot. The employer bears verification costs, provides specified facilities, and recognition continues for three years, subject to mutual extension within the stated limit. Certain Trade Union disputes may be referred to the Tribunal within one year.
