A、You should be absent from work for 2 weeks before you hand in your resignation. B、You should submit your resignation at least

Most American workers, especially those in professional occupations, follow a set procedure when they leave current employment. If you decide to quit, first, you should submit the letter of resignation to your supervisors at least 2 weeks before you plan to leave. When the letter of resignation is submitted, an exit interview with the immediate supervisor is scheduled. During an exit interview, the supervisor may ask questions like "What are your reasons for leaving?" "What can the company do to get you to stay?" and "What advice would you offer to the person who will replace you?" After that, you need to arrange to meet with the personnel manager to settle all personnel items, such as unpaid medical insurance claims and transfer of retirement funds.
    Although employment termination practices vary somewhat from company to company, the 2-week notice is considered standard. If you are employed for certain posts, such as a teacher or school administrator, an even longer notice period, say a semester, may be required so that the school work may not be seriously affected.
    If everything runs smoothly, you will be given a sum of money known as the severance pay. In the United States, employees usually receive severance pay when they are fired or asked to resign. The special pay is designed to provide financial assistance to the employee while he or she hunts for a new job.
