So I realised that if I was dismissed that asking for a grace period wouldn't work if the dismissal is "with immediate effect" and it would just be a waste of time asking.

Aside from what may or may not happen, there's literally nothing for me to do in work now. Yesterday I had some admin work to keep me going, but I asked my TL this morning what to do - he shrugged his shoulders and said I've got nothing for you to do. I said so what WILL I do then? And he told me I could just sit at my desk and play around on the internet.

So that's my current employment status - sitting at my desk messing around online learning myself stuff that's completely unrelated to work, and getting paid for it.
