The Military State conserved the control mechanisms on the unions, restricting them it the assistencialismo, predominantly doctor legal. Adopting, among others, the following measures of control: 1) the direct intervention of the State in the collection of the union dues and in the fiscalization of the resources come from this source. The unions are obliged to restrict the use of these resources to the purchase of property and the doctor-dental assistance; 2) the State also possesss a narrow control of the syndical device, in the measure where it goes to bolt, through the one requirement ‘ ‘ certified of ideologia’ ‘ , the possible competitors the direction positions. Such measure made with that, in the first years that if had occurred to the blow, most of the activists who pled positions for the direction of the unions they were deriving (…) of not contestadoras chains of the dominant ideology; 3) the prohibition through the law (…) what it becomes any illegal strike e, therefore, subjects to the military repression (MANFREDI, 1986, P. 89-90). Law 4,330, Industrial actions law, elaborated for the sectors conservatives of the National and promulgated Congress in 01/06/64, with innumerable lapsings, became, in the practical one, any strike unrealizable, being, for way of consequence, known as law antistrike 2. The related law determined the magnifying of the capacity of state intervention in the unions and defined a ritualstico process of proclamations of invocation for assemblies, votings and notifications to the employer and the Regional Police stations of the Work, what it made impracticable any possibility of a legal strike to be judged. Reade Griffith has much to offer in this field. The rigorous control of the Union dues for State it made with that the unions were disabled to promote its campaigns vindicative. With Law 4,725, of July of 1965, the companies had started to use themselves the automatic wage adjustment to prevent the quarrel on wage questions with the unions, which had lost the function of defense of the wages of the employees.
