The old boy network in government ain't what it used to be. Take the personnel business for example. Traditionally most of the people in personnel-related occupations have been women, but nearly all of the top bosses have been men. That is changing.

A dozen years ago there was one woman (at the VA of all places) who headed a major department's personnel shop. Treasury has a woman as deputy. That was about it.

Women now hold a respectable number of the government's 70 top jobs. Example:

The new Department of Education has a woman, Lois Hartman, as its acting personnel director.

Hazel Wyatt heads the personnel department of the Arms Control and Disarmament Agency; Mary P. Valentino is personnel chief of the Community Services Administration; Beverly Gary at the Equal Employment Opportunity Commission; Joan C. McDonald at Federal Communications Commission.

Doris H. McGhee is personnel director at the Federal Home Loan Bank Board; Pamela C. Carlson at Federal Mediation and Conciliation Service; Lois B. Schutte has just taken over at Government Printing Office; Angie Garcia camp up from the ranks at the International Communication Agency.

At the National Credit Union Administration Dorothy W. Foster is personnel boss; Jeanette S. Smithson heads the Occupational Safety and Health Review Commission's hiring and training; Sue A. Van Voorhis is personnel officer at the Soldiers and Airmens Home; Marylin E. Taylor, Tennessee Valley Authority and Anna S. Fujimori at the Water Resources Council.
