Dear Mr. Kumar,
As you know very well, the probation phase in an employee's career is strictly as per the terms of the contract of employment only on occasions like new hiring and promotion to a higher cadre within the organization. It is not a statutorily prescribed condition of employment but for the guidelines provided in the Model Standing Orders under the IE(SO) Act, 1946 as of now.
Since probation is a phase of orientation for the new appointee to the organization and a test of his suitability for the job position offered, it cannot be indefinitely long. Hence, the provision for extension of the probation period in case of a shortfall in the employee's expected overall performance and a formal declaration by the employer in this regard.
Therefore, the declaration of satisfactory completion of probation followed by an order of confirmation is a matter depending on the subjective consideration of the employer. No probationer will acquire the status of a confirmed employee automatically by the efflux of time. Of course, it is possible if there is a provision in the contract of employment for deemed confirmation after the lapse of a stipulated period of time without formal orders either way by the employer.
When the employer simply keeps silent on the matter indefinitely, what would be the remedy available to such an unfortunate employee kept as a probationer for years? The employee, if he is a workman, has to invoke the provision of sec.25-T of the IDA, 1947 against the employer for committing the unfair labor practice enumerated at sl. no. 10 of Part I of the fifth Schedule of the Act.
