A live, locally produced, televised job fair will be aired 8 to 10 p.m. Friday on WDCA-TV (Channel 20) in an effort to link unemployed viewers in Maryland, Virginia, and the District with jobs in the area.

Two hours of regularly scheduled programming are being preempted to present "Job Fair," and local employment commissions have pledged their cooperation and support, station officials said. WDCA-TV will join other Taft-owned stations around the country in the corporate-sponsored program.

The program format will resemble that of a fund-raising telethon. Many jobs already have been pledged, but those who want to pledge jobs during the telethon may call 951-0120 between 8 and 10 p.m. only. Employers who want to pledge jobs before the telecast may call employment commissions at 949-3002 in Montgomery County and 441-4919 in Prince George's County.

People seeking jobs can call 951-0120 during the telethon between 8 and 10 p.m., and their re'sume's will be taken over the telephone. They also may appear in person to fill out re'sume's between 10 a.m. and 10 p.m. the day of the telethon at Wheaton Plaza, a live remote broadcasting location where employment commission personnel will be.

Before the telethon day, people seeking jobs also may call or appear in person at the Maryland Employment Security Administration, where special re'sumes' will be taken.

After the telecast, a computer will match applicants with job openings. Re'sume's then will be sent to employers, who will contact applicants.
