Anybody can go and find other employer in this country as long as he/she got the NOC ( No Objection Certificate) from her/his current employer. In your case my friend,you have a contract in which you agreed all the terms and conditions stipulated in the contract.
Then now you are complaining about the policy of your company.
Do one thing, talk to them (hrd)and ask about your complaints.Maybe they will listen. Good luck!!!
