Letter of appointment is a crucial document in service jurisprudence. A bald letter that a person is appointed does not carry any meaning. A mere statement that a person is appointed as a probationer or as a temporary or is subject to the rules of service which are in vogue is not enough. The letter of appointment shall be acknowledged and accepted by the employee. While admitting him to service the employer shall serve on the employee the set of rules governing the conditions of service and his acceptance of the same is obtained. The employer shall also obtain from the employee an unequivocal declaration as to the truth of all the facts stated in the application for the appointment such as the date of birth, qualifications, and the caste if the employee belongs to reserved category. If the letter of appointment or the rules do not provide for suspension, pending enquiry or does not provide for retirement age, it may become very difficult to proceed against him for suspension, pending enquiry or for retirement. The employee may claim that he is not liable to interim suspension or liable to any retirement so long as he is able to render service. A person may be appointed temporary or adhoc. It should be stated in the letter of appointment whether such person is appointed temporary pending confirmation or temporary in a post temporarily created. An adhoc employee may be appointed in a vacancy created for a particular assignment or pending joining of a regular employee till the latter joins the duties. This fact must be clearly stated to the employee before he is appointed. Salary and its grade shall be specified in the letter of appointment and also the cadre to which he belongs. They shall not be changed after the employee joins service to his detriment. The condition about his transferability shall be brought to the attention of the employee so that he may be transferred from one place to another or from one post to another of the same cadre. If an employee is appointed as an apprentice or trainee, it shall be made clear to him that unless he completes successively the apprenticeship or training he is not entitled as of right to be absorbed in the regular service.
