My colleague recently has been select as manager. despite he is incompetent comparison to me on every aspect?

i am computer programmer. and recently my colleague has been selected as manager over me but he is not given enough rights to have control over me. yet he can control my attendance and deduct my salary when ever i wanted to take leave i must ask him for the same and he must approve my leave application. it is disgusting. every time i ask for the same from my general manager he said that nobody has offically given rights as manager and it is test period. and when i say that he always try to annory me on every occasion he said you must carry on and finished the project you have in your hand. what i am asking is what is going to happen to me at the end? does this desperation is going to continued. owning to the fact if i take the management postion it would affecting so that the project may be never be done.
