Trending @Accenture; Can we take optional holiday during notice period?

By all means you can take not only optional holiday but also youncan avail all kind of leaves.

If anyone says it's not allowed, ask them you understand policies otherwise, and also ask them put in mail.

Because this is hollow threat .

Yes bro, I'm taking casual leaves, sick leaves and had a planned leave on 4th

Only sick leaves

All kinds of leaves you can take. No restrictions on that .
But your manager should approve your leaves
