Public relations specialists, also called communications specialists and media specialists, handle an organization’s communication with the public, including consumers, investors, reporters, and other media specialists. In government, public relations specialists may be called press secretaries. They keep the public informed about the activities of government officials and agencies.
Public relations specialists must understand the attitudes and concerns of the groups they interact with to maintain cooperative relationships with them.
Public relations specialists draft press releases and contact people in the media who might print or broadcast their material. Many radio or television special reports, newspaper stories, and magazine articles start at the desks of public relations specialists. For example, a press release might describe a public issue, such as health, energy, or the environment, and what an organization does to advance that issue. In addition to publication through traditional media outlets, releases are increasingly being sent through the Web and social media.
Public relations managers review and sometimes write press releases. They also sponsor corporate events to help maintain and improve the image and identity of their organization or client.
In addition, they help to clarify their organization’s point of view to its main audience through media releases and interviews. Public relations managers observe social, economic, and political trends that might ultimately affect the organization, and they recommend ways to enhance the firm's image based on those trends. For example, in response to a growing concern about the environment, an oil company may create a public relations campaign to publicize its efforts to develop cleaner fuels.
In large organizations, public relations managers may supervise a staff of public relations specialists. They also work with advertising and marketing staffs to make sure that advertising campaigns are compatible with the image the company or client is trying to portray. For example, if the firm has decided to emphasize its appeal to a certain group, such as younger people, the public relations manager ensures that current advertisements will be well received by that group.
In addition, public relations managers may handle internal communications, such as company newsletters, and may help financial managers produce an organization’s reports. They may help the organization’s top executives by drafting speeches, arranging interviews, and maintaining other forms of public contact. Public relations managers must be able to work well with many types of specialists to accurately report the facts. In some cases, the information they write has legal consequences. They must work with the company's or client's lawyers to be sure that the information they release is both legally accurate and clear to the public.
How to Become One: Public relations specialists typically need a bachelor’s degree. Employers usually want candidates who have studied public relations, journalism, communications, English, or business.
For public relations management positions, a bachelor's degree in public relations, communication, or journalism is generally required. Courses in advertising, business administration, public affairs, public speaking, political science, and creative and technical writing are helpful. In addition, some employers prefer a master’s degree in public relations or journalism. In 2010, one-fourth of public relations managers held a master’s degree.
