To hand in my notice via email..

[crumbleorbreadcrumbs]

I only work 2 days a week, and only work with the manager 1 day a week. I have this week coming off meaning I wouldn't be able to see him in person until w/c 19th and I just want to get it handed in and done. I could go through and drop it off but there's no guarantee he'd have time to talk.
AIBU to just hand it in via an email?

Not at all. I don’t think I’ve ever given or received notice in any other way, tbh. I think that’s fairly standard.

I thought that’s the normal way? Maybe I’m wrong. I’ve always sent email CCing HR and after I’ve had a talk with my manager, so he/she was not blindsided 😅

Could you tell him via email and say you are happy to follow it up with a formal letter if required?

Common practice (in my industry) would be to include the formal letter as an attachment.

I agree TBH, but I am from a different era and sometimes what I think someone should do bears no resemblance to what everyone else thinks 🤣

I've only ever handed a physical letter in person as a notice. I think it's going to be easier to do it in email and maybe say feel free to ring me.
I was offered the job via email so don't see the difference!

I've not handed an actual letter in ever, always an email.

Email is fine. No-one needs paper letters for much these days.

I handed in my notice last time via email, well it was a letter attached to an email, but about a month after I'd been offered my new job as I needed to wait for the contract etc. My boss knew I had got a new job already of course!
Assuming it's not going to be a big surprise for your boss, I would just put it in an email and copy in HR.
It was weird, up until then I'd always done a physical letter with a wet signature!

No this is the thing.. it would be a total surprise to my boss.

In which case, have a conversation in person or by phone to let them know. Especially if there's an outside chance you might need a reference.

Be a decent person and speak to your boss first, even if by phone.

If you haven’t mentioned it to your boss yet, then you will need to wait to speak to him. While it’s understandable that you want to get it over with ASAP, it’s worth remembering that you may need a reference in the future. So it always pays off to end on good terms.
We once had a member of staff walk out with a massive bang right in the middle of the working day and another called in sick at the busiest time of year (and their SM suggests they were enjoying themselves on a holiday) and then resigned via an email. We thought that would be the end of it but 6-12 months later we received requests for reference for both of them and we had to be open about their conduct.

I haven't been there much longer than 6 months so in terms of reference, I think I could probably miss it off my CV and just say I was having a career break to look after the children. I just want to leave asap and waiting to see him delays it by about 2 weeks

Can you not just give him a ring first thing Monday and then send it?

Email is fine, but I agree that it is courtesy to let your manager know verbally first.

A few years ago I had a manager who went on two weeks leave and came back to four emailed notices. Obviously there was a reason for four notices at once, but I still think that was pretty shitty behaviour.
