Dispatching Washington-based bureaucrats to the nether regions is frequently a sign that an administration has designs on their jobs at headquarters. But when the National Labor Relations Board flung two of its Washington officials into the field as regional directors this week, there were smiles on their faces.

The regional directorships, solicitor Willie L. Clark Jr. said, "are the best jobs."

Clark, who has been with the NLRB in Washington for 10 years, will run the regional office in Winston-Salem, N.C., and assistant general counsel Gerald Kobell will pack up his desk and move to the regional office in Pittsburgh.

Three employes already stationed in the field will be promoted to regional directors--Robert H. Miller in San Francisco, John D. Nelson in Seattle, and Louis J. D'Amico in Baltimore. All the jobs are Senior Executive Service positions, awarded after an application and review process.

Meanwhile, NLRB chairman John R. Van de Water is still going through an application and review process of sorts himself. He's holding down a recess appointment because his nomination to a permanent seat on the board didn't make it through the Senate Labor and Human Resources Committee last fall.

President Reagan resubmitted the nomination, but Van de Water's chances for the permanent seat dimmed perceptibly last week when he aroused the wrath of the National Right-to-Work Committee by voting not to seek a Supreme Court review of a ruling restricting the Florida "right-to-work" law. The vote infuriated Reed Larson, president of the committee, who said he may oppose reviving Van de Water's nomination. The Labor and Human Resources Committee is chaired by another "right-to-work" supporter, Sen. Orrin G. Hatch (R-Utah).
