The standard and widely used method for formally resigning from a job is through a twoweek notice resignation letter. Please, be aware that in Michigan, employment is typically considered "atwill.Dear (managers name), Please accept this as my formal resignation from my position as a (position you held) from (company name). Most employers ask that you give them two weeks' notice before walking out the door for good. State your resignation. Short and to the point. Basically, "a thank you to your current company for the opportunity" and "a departure date" two weeks from the email. A two weeks' notice is a short letter or email that formally tells your employer that you're leaving and when your last day will be. If a employee wrote a involuntary resignation letter with a two week notice will she qualify for unemployment in Michigan? The recommended timeline for providing a resignation letter is at least two weeks prior to your planned last day.
