Abstract:

Provide your boss and the personnel department with a copy of your resume each time you update it. They will be interested to learn about any educational or training programs you've completed, changes in your current job responsibilities, new professional or civic organizations you've joined and any technical skills you've acquired since starting your current job. A resume should also reflect special accomplishments and your on-the-job performance record.
