Huge vacancies have compromised the Railway's safety measures. According to All India Railwaymen's Federation, there are around 13.26 lakh on-roll employees in Railways of which almost 75 per cent fall in the safety category. While the 1.22 lakh unfilled vacancies make up for roughly 12 percent of the employees in the safety category, Shiva Gopal Mishra, general secretary, AIRF said that almost 15 percent of the posts are vacant on a continuous basis and there has been no improvement in the situation. "Sizeable vacancies in the safety category not only compromises the safety of the trains and their operations but also puts an additional workload on the existing employees which is not a happy situation," said Mishra. Though the Railway administration and the board claim that they are working hard to fill the vacancies, insiders say that it is both management failure and also a result of employing overqualified individuals which have resulted into high attrition rate. While safety category employees are the frontline of railways especially in departments such as loco-running, operations and even maintenance, a high number of vacancies means additional work for existing employees.
