8. There is no rule of thumb that in every case where the Industrial Tribunal gives a finding that the termination of service was in violation of Section 25-F of the Act, entire back wages should be awarded. A host of factors like the manner and method of selection and appointment, i.e., whether after proper advertisement of the vacancy or inviting applications from the employment exchange, nature of appointment, namely, whether ad hoc, short term, daily wage, temporary or permanent in character, any special qualification required for the job and the like should be weighed and balanced in taking a decision regarding award of back wages. One of the important factors, which has to be taken into consideration, is the length of service, which the workman had rendered with the employer. If the workman has rendered a considerable period of service and his services are wrongfully terminated, he may be awarded full or partial back wages keeping in view the fact that at his age and the qualification possessed by him he may not be in a position to get another employment. However, where the total length of service rendered by a workman is very small, the award of back wages for the complete period, i.e., from the date of termination till the date of the award, which our experience shows is often quite large, would be wholly inappropriate. Another important factor, which requires to be taken into consideration is the nature of employment. A regular service of permanent character cannot be compared to short or intermittent daily wage employment though it may be for 240 days in a calendar year.”
