Under what conditions can a trade union apply for compulsory recognition?

To apply for compulsory recognition, the union must be independent of the employer; the employer must employ at least 21 workers; there must not already be a collective agreement under which a union is recognised to conduct collective bargaining for the same group of workers; the Central Arbitration Committee must be satisfied that at least 10% of the workers in the bargaining unit are members of the union and that the majority of the workers in that unit would be likely to favour recognition; there must be no competing applications for recognition by another union or other unions unless they can show that they would cooperate on behalf of the workers; and no application must have been made for recognition within the previous three years in respect of the same group of workers.
