Put in PIP 3 months after joining and being asked to resign

Respected lawyers, I am seeking some authentic legal advice on a matter related to my current job. I have tried talking to people and researching on internet but I am still confused. It would be great if I could get some advice from someone who actually knows labour law. This is the situation: 1. I was hired by a leading MNC (based out of US) on Mid-July 2016. The job is based out of Gurgaon. Probation period for the role is 6 months 2. During the first three months, I was ramping up on the training materials. I also traveled for around 6 weeks during that time for training and to get to know the team in other countries 3. Little over three months, On 27th of October 2016, I was put under a PIP (performance improvement plan) which I signed 4. I don't think it's is a performance issue as no one can judge someone in 3 months but it may be my point of view only and pvt ltd companies I suppose are free to hire and fire at will 5. And little over 1 month into the PIP, the HR is giving me option to resign and get a garden leave of 1 month during which I won't need to come to office and I would get the salary and insurance for the month. It was communicated to me on video conference and not in written communication 6. I am quoting some points as per my contract: 6.1. You will initially be on probation for a period of six (6) months from the Commencement Date, after which your performance and conduct will be reviewed and if found to be satisfactory, your appointment will continue on the terms set out in this Agreement. If your performance or conduct is found to be unsatisfactory, the Company may in its sole discretion extend your probation for up to 3 (three) additional months. During the period of probation, your employment may be terminated by the Company without notice or with notice required by law as then in effect, whichever is greater, or payment of base salary in lieu of notice. 6.2. Relocation Package: The Company will provide you with relocation benefits as specified in a epa-rate relocation letter (“Relocation Benefits”). The Relocation Benefits are contingent on your being employed by the Company and remaining so employed for a period of 12 months from the Com-mencement Date. If you leave the Company for any reason within 12 months of the commencement Date, you must repay the value of the Relocation Benefits on a prorated basis (based on the number of months remaining until the said 12 month period expires) So, I just wanted to know: 1. if the employer is doing something which may be not lawful and if not, what should I do? 2. Should I resign or go on with PIP and get terminated for failing the PIP? (I don't think the PIP is to give me a fighting chance but to give the employer a documented proof to avoid any legal issue) 3. Also, If I resign I would be asked to pay the pro rated relocation package (as per the contract) that company spent on me which would be quite high 4. I am not sure if I would be asked to pay the same even if I get terminated Please provide your ever valuable advice on the matter. I will be grateful. Thanks
