Two weeks notice, without the ambiguity
Most two weeks notice disputes come down to one thing: nobody named the exact last day. This letter names both dates explicitly, so there is nothing to interpret and nothing to argue about later.
14 calendar days, not 10 business days
By convention, two weeks notice means 14 calendar days from the day you give notice, weekends included. Some people read it as 10 business days, which lands on a different date. The fix is not to debate the convention: name the exact last working day in the letter and the ambiguity disappears.
Name both dates explicitly
State the date your notice begins and the date of your last working day. A letter that says only "two weeks from today" leaves the math to whoever reads it. A letter that says "my last working day will be Friday, July 24" cannot be misread.
You usually do not owe notice by law
US at-will employment generally lets you leave at any time. Two weeks is a professional courtesy, not a legal duty, unless your contract says otherwise. The reason to give it anyway is simple: references and reputations outlast jobs.
The email subject line that works
If you send the letter by email, use a subject that files itself: "Resignation, [Your name], effective [date]". It is unambiguous for HR, easy to search later, and impossible to mistake for anything else in an inbox.
Same-day walkouts happen
Some employers accept notice and end employment the same day, especially in roles with sensitive access. Whether the notice period is paid out depends on company policy and state law. Give notice only when you are ready for that outcome.
