thanks jackmohan... but anyway ithink my manager do that kind of stories because ive been employed in my company for more tahn 2 years and he promis me a promotion of work but he did not give, after that i show them that i have offer in another company that can make my salary double and he said that they will not be giving any release. so, i said that i will go to the labor if they dont want me to give a noc. after that, it happened as i mentioned above.
