I would say that if they are genuine trainees you should not give any outstation allowance which is available to permanent workers. If you think that as part of training program they have to work in another plant, you can incorporate the same in the training program itself and the trainees are expected to manage the show without any special allowance from the company. By paying anything extra you will be establishing yourself that for your business requirements you need the trainees to work in another plant and this will later on become an evidence to show that the training is just for name sake but in practice all are regular workers only. It will be worth reading the court ruling in Sree Ram Narayan Mills Ltd vs Employees Provident Fund in which the Court has observed that It is clear from the decision of the Division Bench of this Court, cited supra, that the apprentices, who are doing the regular work, ought to be considered as the employees of the establishment concerned and not mere apprentices.
