On your last day, you should submit any final timesheets or expense reports that you may still have and make sure to return all company property or documents that you took home during your employment. You should also schedule meetings with your supervisor, HR representative, or other key individuals to ensure that all necessary paperwork is completed before leaving. Finally, make sure to give proper notice to all of your coworkers and write a thank you note to show gratitude for their help during your employment.
