Anyone, please guide me on employees' personal travel expenses in Naxalite areas (Gadchiroli) for those who reside at the plant and visit their families thrice a year. The trips are from Gadchiroli to Mumbai, Chennai, or Hyderabad. How much should we allow in terms of amount, and what type of fare should be provided - air, train, or road? Additionally, please advise if the employer has to cover the personal travel allowance expenses.
