I handed in my notice on Friday morning. I sent it directly to my manager, marked the email as high importance and CC'd the UDL for the project. However as of now (midnight on Monday) neither of them have even acknowledged that I've handed it in.
My manager is just casually handing me tasks like normal and ignored any follow up emails about me leaving. She's actually been a great manager and has never been like this before so I have no clue what's going on or how to handle it.
I also emailed someone from HR today just asking if they were aware I had handed it in, as with other colleagues they got an email from HR within hours after handing it in. They also need to conduct exit interviews within 3 days of someone handing their notice in. HR have also not responded.
Don't get me wrong, I know I'm leaving on the date I specified. But I'm working on a high security project and we have procedures for leaving that need to be started by both management and HR, and as far as I'm aware HR have literally no clue that I've even handed in my notice.
