Why did president truman veto the taft-hartley act

The Taft-Hartley Act was proposed overriding the veto by President Harry S.Truman. Congress passed the Taft-Hartley Act in 1947 to control the power of labor unions. The Act made sure to stop the labor Unions contribution in a political campaign and also prohibited disclosure of a union's financial activities. President Truman vetoes the Taft- Hartley Act because he believed that it was against the working-class people in America. It abuses the rights of the people who needed Unions for better wages and working condition.    

the fact that could also be added to column b is that during world war ii, specifically between the years 1941 and 1945, japan expanded its territory towards the indonesian territory in what was known later as part of the "pacific war". in that time, japan could conquer the philipines, singapore,   borneo, central java, malang, cebu, sumatra and various other islands of the area, therefore expanding its territory for a brief period of time.
