Continuance of paid employment under the same employer or elsewhere is a matter of personal choice as well as discretion of the employee concerned. Therefore, restrictions, if any imposed by the employer in order to reduce attrition by way of notice or payment of notice salary in lieu thereof, facilitate finding a suitable substitute and to recover the cost of training, if any incurred in the event of the trained employee's failure to fulfill the stipulated minimum post-training service should be reasonable as well as justifiable. When these conditions are fulfilled by the out-going employee with the due approval of the employer, formally or informally the employer can not impose fresh conditions like the ones mentioned in the posts. Paid employment can not be converted into a system of slavery suiting the whims and fancies of any arrogant employer.
