If I have taken resignation back in tcs, but now when can I resign again?

I personally know my friend resigned again after one month. There's no cooling period. But it's not a good practice.

I have similar question so I asked my HR and she fave some vague ans " resignation can't be repeated process" and I have one friend who is also HR in TCS and she said we can resign back immediately. I asked some people here on grapevine and they were saying 6 months is the resignation cooling period . I don't understand who is right here. If u get any info please let me know

There is no cooling period for resigning again. You can resign whenever you want. But this time they may not allow you to revoke it if you change your mind again. So only resign if you are 100% sure
