So i joined this company a month back they took my interview and sent an offer by mailing it just a written text on email with ctc disclosure , they didnt formulated any prefect offer letter on letter head where i have signed and accepted and they have sent me with proper company seal . So after joining the company i still didnt get any offer letter as they told me that candidates would leave the company by negotiating with other company so they didnt provide me offer letter and similarly it went one month and i didnt receive my appointment and now they are telling me that i need to adher the rules and regulations of the policy ? can they take any legal actions against me when they didnt provide any offer or appointment letter although they have given one month salary by cheque does this i m the employee of that company . please reply as soon as possible .Thanks in advance
