Teacher dissatisfaction with representation by the four Trinidad unions had grown in the 1970s. There was the view that adversarial relations between the three units had severely hampered Industrial Relations in the Teaching Service. As early as 1966 there was a struggle between two of the three unions to be the sole representative for any class of, or classes of teachers. The Special Tribunal No. 10 of 1974, which stated that any one of the three unions could represent any class or classes of teachers decided this issue. This resulted in rapid changes of membership among teachers. However, not one of these unions emerged as the majority union.
