File an unemployment compnsation claim and your employer will have to file a separation notice. Also request one in writing from the HR department at your former place of work.
There is no good answer to this question. I agree with the former response that you should apply for unemployment insurance, in response to which most employers will (but not always) issue a separation notice. The GA Department of Labor has a rule which requires employers to issue a separation notice within 3 days of a separation, but the Rule has no penalty if an employer fails to comply with the Rule.
