Trending @Accenture; Can we take resignation back in Accenture?

Someone who is at CL5 told me that accenture is not allowing to take the resignation back looking at current conditions

You can take back till LWD, but your reversal needs to be approved by DU lead, if your DU lead say there is no role for you, then no reversal will happen.

Days are gone when HR used to put you in other projects

Yes, 5 days prior to lwd

Any fresh experiences or comments?
