I am writing to inform you of my two weeks notice. Effective August 18th will be my last day.Specify your last working day within two weeks from the notice date. Clearly state the final day to avoid misunderstandings. Do I have to give my employer two-weeks notice? Write a letter of resignation giving your notice term, then hand it to your manager in person with a polite and professional explanation. Basically, "a thank you to your current company for the opportunity" and "a departure date" two weeks from the email.
