You are obviously referring to Spice and I will stay as far away as possible from this HR outfit. There is an impending exodus of expats from here because of.... well.... a complete disconnect from the realities of the current market.
They do not know how to treat flight crew, local and expats, and they are paying the price with almost daily delays and cancellations because of lack of crew. Flight crew are grappling with rostering, accommodation and pay issues and the dimwits in HR have no idea what's about to hit them. Do not expect anything from flt ops as they are just there to rake in the moolah and HR has them on a tight leash.
The contracts are vaguely worded and be rest assured that any contentious issue will lead to an interpretation of your contract in their favour.
And a word of advice about your PF. Your AND the company's contribution comes from your salary (which they won't tell you in reality is CTC). Also a new rule has been implemented where no foreign citizen is allowed to withdraw the monies from your PF until the age of 58. You have to maintain an ACTIVE Indian bank a/c during this whole period and will have to return to India PERSONALLY to collect the money.
Indian airlines are not all bad. I would recommend Jet over Spice. Most of your issues are Spice specific. The medical is a tuffie and has to be negotiated, same as China. And living here is not easy.
