Do I need to write a letter of resignation?

[hubes]

I am formally announcing to my board of directors that I'll be stepping down in a few months.

They can't take any action tomorrow, as it isn't on the agenda, and I'm not planning on leaving until late December.

Do I need to write a formal letter for tomorrow?

[snipsnsnails]

Yes

[frauschmindy]

I would, yes.

[PinkSquirrel]

I would let people know as soon as possible, ideally, tomorrow and if there's no time on the agenda then I would write a letter.
