Trending @HCL; If the client wants to hire me on their payroll will HCL allow me if client insists?

Simply resign and take offer from client

No need to be a hero and informing your RM and colleagues.

HCL won't allow. Just resign, keep it as secret. Serve notice period and join.

If they pay you more then HCL then client have to wait for 3 months and there is non compete agreement also which may cause issue for you.

Yes, ask them to buy you
