NOTHING will happen.
Cosatu et al are self-serving parasites on the poor and the workers and in their acceptance of the patronage of those in power - their bluster, if not intentionally so, merely serves to distract and make think people think they care.
Even if various honorable organs of state do want to do something about this mess they will be hampered by all the compromised individuals at all levels who will run interference - again either intentionally or inadvertently through ineptitude and inaptitude having been placed in important posts by nepotism or, again by the inapt-/ineptitude of those making the appointments. 
I am reminded of the time and distance required to stop or turn a huge supertanker - by the time the object of the exercise is achieved there has been plenty of time for the rats to abandon ship or create another diversion.
