As a human resources or HR administrative assistant, your job is to support various management-level employees and conduct record-keeping within a business. HR is a sensitive department that often handles highly personal information, so you are expected to work with the utmost degree of professionalism and respect for privacy. As an assistant, you are not in charge of making too many decisions on your own, but you may participate in the decision-making process. Your duties may include assisting with managing payroll, hiring and training a new employee, organizing a staff recruitment event, or researching a candidate for employment.
