i saw your profile and you have completed 2 years already. you quite lucky that you have gone this far. in my case, i resigned after such deliberate confrontation with the management fighting for what i think is right. but nothing has change so decided to do the resignation. the worst case is that when i ask the hr to use the guarantee fund (actually its my money equivalent to one month salary i've worked and deducted in first month at the company) and they didn't agree to my appeal. so i cannot go home to the effective date of my resignation. how bad? i guess they are using my money investing it for their own sake!
