Dear Jocoba,
A contract of employment need not be in writing. Initially, you were offered a job in the organization subject to your acceptance of the terms and conditions mentioned in the offer letter addressed to you which you had accepted and joined the job. Thus an implied contract of employment is created and is in existence. Therefore, a separate appointment order is not necessary unless it is stipulated in any employment law. Further you would have been paid the salary as per the offer letter. Therefore, it is futile to argue that an offer letter is not a contract but only an invitation to the job. Moreover, the contention to leave the job without serving the notice period mentioned in the offer letter after acting upon the other conditions therein would tantamount to approbation and reprobation which is not admissible in Law.
