You want to give at least a two weeks' notice. The employee's written request must be made within 15 working days of termination.MN: Gave 2-week notice to employer, taken off schedule immediately, now being told they won't pay out my PTO due to not giving 30-day notice. The employer is not legally obligated to accept that offer and may immediately accept the resignation or accept shorter than the offered notice. You must give appropriate notice (in most places it is 2 weeks, but in some companies it may be a month), and then you're done. When resigning without notice, your letter should state clearly that the resignation will be effective immediately. Please accept this as my formal notice of resignation from my role as a talent acquisition specialist. In the body of the letter, immediately state your intention to resign and provide your reasoning, including only positive feelings towards your work experience.
