行政助理 人 串行

A secretary, administrative assistant (AA), or administrative professional is a person whose work consists of supporting management, including executives, using a variety of project management, communications, business administration, public administration, office management, mailroom operations, property management, receptionist, light security, records management, and/or organizational skills. In the modern era, they also tend to actively participate in the professional service work of the organization, such as having a hands-on involvement on the production of deliverables, other work products, and conducting other similar professional duties.

Some high-level administrative professionals, support staff personnel, or those that work in "General Administrative, Clerical, and Office Services," as well as those in an entry-level position that requires specialized knowledge preferably or explicitly acquired through a higher education university degree in a field pertinent to the organization's industry are specialized secretaries or specialized administrative specialists in the general sense while others can be further sub-categorized into many other titles. Depending on a company's organizational structure, the most senior administrative professional (with managerial authority) may be referred to as an office manager or chief of staff, though chiefs of staff tend to have additional responsibilities; administrative professional that work directly under a senior executive or c-suite executive are generally referred to as executive assistants.

Personal assistants (PA), as well as executive assistants (EA) and special assistants (SA), generally work directly with an individual executive. Personal assistants tend to have duties that assist the executive in both their personal and professional lives while executive assistants and special assistants tend to focus on assisting the executive solely in their professional capacity. They may also be in charge of sending and receiving correspondence, as well as greeting clients and customers.

This role should not be confused with the role of an executive secretary, cabinet secretary such as cabinet members who hold the title of "secretary", or company secretary, all which differ from an administrative assistant.
