What employment can someone obtain if they were not given the PhD after studying and publishing?
Congratulations on the publications you have achieved thus far. 


  If I change my advisor now, my present advisor will become vindictive. [...] A students fate depends on her advisor; higher authority cannot do anything.


It sounds like your best bet, if you want to stay where you are, would be to avoid conflict with your advisor.


  I am in my 3rd year of phd.


I don't know anyone who completed a PhD in two or even three years.
