I need to send mine in tomorrow and idk how to write it. Do you gotta be formal or does it just have to say "2 weeks and I'm gone"?

Are you leaving amicably and using the company for a reference?

Short, simple and sweet would be my recommendation. "To whom it may concern, this is my two weeks notice. My last day will be (insert date here). Thank you, (signature and date)."

If you're leaving amicably, you can add a line or two complimenting the company and expressing your thankfulness for your time there.

exactly what @interesting said, short sweet and simple. no need to post reasons or anything like that

Alright, sounds good to me. Thank you!

Even better, wait two weeks and then turn in a two weeks notice that's retroactive for two weeks, and walk out immediately

No smart ass has said : with a pen, doc

I loved our time together, but I found someone else?

What @interesting said
Like pretty much copy what he said and you'll be golden. I've quit from 2 different jobs and that's worked well.

depending on the laws in your area it doesnt really matter as long as you give it as in most places its illegal for the reference company to say anything other than "yes [ex-employee] worked for us from [date] to [date2]"

This is all great advice. From a formatting point of view, I would add a few quick things: 1) put their address in the upper-left corner, 2) put your address/phone/email under it, and 3) put the date in the upper-right corner. And finally, end it with "Best regards," or "Sincerely," and then several spaces and then your printed name. In the spaces, sign your name. Congrats!

@jasonmon I literally wrote my 2 weeks on a napkin XD

As long as you have a good relationship with your boss, you could simply write "This is my 2 weeks notice, my last day will be x" and then make sure you sign and date the paper

Bake it on a cake, then at least you can go out with some goodwill on your shoulder, it’s a nice conversation starter and come on who doesn’t like cake. Just make sure to take pictures of it to make sure they can’t say you up and walked out.
