In a business world sense, a personal assistant is a trusted junior employee who assumes the role of an executive's chief-of-staff. Many of the everyday tasks necessary for an effective workday fall on the personal assistant, from scheduling meetings to arranging transportation. A personal assistant is also expected to screen incoming calls and messages, assign tasks to other junior employees and prioritize his or her employer's schedule. Running personal errands or setting appointments may also be part of a personal assistant's duties.

Becoming a personal assistant may be a case of being in the right place at the right time. Once an executive decides that hiring a personal assistant might be a necessity, he or she will often look within the company first. Employees with secretarial experience or a proven track record for loyalty may be the first ones considered.

There is no specific educational or job track that leads to the role of personal assistant. Having a strong work ethic, displaying self-discipline and proving an ability to multi-task under pressure are all good attributes for the position. Many executives and managers look for a good personal rapport between themselves and potential personal assistants.

As tempting as the position of personal assistant may sound, there are some drawbacks to consider. The average personal assistant may put in anywhere from 40 to 80 hours a week or more. If the executive decides to attend a week-long business seminar out of town, the personal assistant may have to accompany him as well or assume additional duties at the office. The average salary for an entry-level personal assistant may reflect his or her junior status, even if his or her employer is compensated well by the company. If the working relationship becomes strained, the role of personal assistant can become very stressful indeed.

There are also some benefits of being a personal assistant to consider. Personal assistants are often in a position to interact with high-level executives, which could lead to an inside track on promotions or other job opportunities. Executives may also invite a personal assistant to attend business dinners or private parties. Vacations for executives often become a working vacation for a personal assistant, with paid travel and an expense account. Working for a well-known businessman or celebrity can also be a social perk, with invitations to movie openings, concerts or other high-profile events.
