ABC's ''Homefront'' is a rare network show that deals with working people and unions in a serious manner. Writing in the AFL-CIO News, Candice Johnson says the show treats workers of the late 1940s ''with dignity and respect.'' The show airs 8 p.m. Thursdays.
Janice Gretemeyer, ABC's vice president for public relations, said Thursday from New York that the producers ''tried to convey the activities and the mood of that time period, and obviously it was a very strong, emerging time for the unions, with the return of so many GIs from the war.''
The audience, surprisingly, is a young one, with the core group between 18 and 49 and with a majority of women, Gretemeyer said. She said the decision to renew it for a second season ''was based on the fact that it had a loyal core audience and got a great deal of critical acclaim.''
