I will be your office assistant for 2 hours. Office assistants' job duties vary, but usually include tasks like typing, filing, taking inventory, keeping records and creating excel sheets. They may also prepare documents, process mail and answer telephones. Some office assistants perform data entry and payroll tracking. Assistants might also work with salespeople, deal with customer complaints and answer questions about business services. While office assistants may perform many of the same job duties on a daily basis, some responsibilities can change from day to day according to the needs of the employer. Office assistants in entry-level positions who have strong analytical, people and communications skills often have opportunities of advancing to supervisory roles after gaining some work experience. They may also be promoted to other office or administrative positions with higher levels of responsibility, such as office manager or administrative assistant.
