Abstract:

A survey of CEOs, corporate spokespersons, and media representatives suggests that the evolving roles and responsibilities of corporate spokes-persons may result in greater opportunities for technical communicators in corporate public relations. However, these opportunities require communication principles and skills that have not traditionally played a strong role in technical communication education. This essay discusses these requisite considerations so they can be more explicitly addressed in the contemporary technical communication curriculum.
