The 4,455-job cutback predicted for the government this summer in metro Washington will take place in agencies and departments that employ 128,000 of the 362,000 civil servants here.

Department of Health and Human Services, which had 34,510 workers here as of February (a drop of about 300 from the previous month) is due to take the biggest cuts. The Federal Government Service Task Force estimates -- based on data supplied by HHS personnel brass -- that 3,000 employes will get RIF (reduction in force) notices and that 2,580 will actually be separated.

The task force data are the best available now. The number of employes due to be laid off will change, agency-by-agency, depending in large part on the attrition rate over the next few months. The more people who retire, the fewer who will have to be fired.

Commerce is predicting that it will send at least 500 RIF notices to its 20,000 staffers here, and about 500 willbe hit by layoffs.

Department of Transportation is planning 328 RIF notices, and layoffs of around 275. It has just over 10,000 workers.

Labor Department with 7,800 workers here, will send RIF notices to 55 but anticipates only 27 layoffs.

National Aeronautics and Space Administration will send out 150 RIF notices to its 5,000-plus workers here, and expects to lay off 20 people.

National Credit Union Administration will be hard hit, sending out 50 RIF notices and laying off about 20 of its 290 staffers here.

Treasury is planning 18 RIF notices and a layoff affecting only eight of its 18,000 local employes.

Consumer Product Safety Commission, which has just over 600 people here, will send RIF notices to 75 people here, and lay off about 35, according to current estimates.

Equal Employment Opportunity Commission reported that it will send out 36 RIF notices here, and plans to lay off 24 employes. EEOC has about 840 local employes.

Housing and Urban Development officials told the congressional task force, headed by Rep. Mike Barnes (D-Md.), that it will pass out 130 local RIF notices and that about 65 of its of its 4,600 local people will be hit by layoffs.

Interior is predicting RIF notices for 55 of its 10,500 people here, and local layoffs of 51.

Interstate Commerce Commission (1,360 local workers) believes it can limit its layoff to one part-timer.

The task force figures do not include the Water Resources Council, which has 62 metro area workers. As reported here May 26, the council has already send RIF notice to its entire staff. If Congress does abolish the Community Services Administration, most if not all of its 400 workers here (360 are on the RIF list) will be laid off.

RIF actions and actual layoffs will be spread unevenly, some agencies being hit hard and others untouched. Office of Personnel Management, for example, does not anticipate any layoffs although a major unit of the agency dealing with grants is being abolished.

In some agencies, large numbers of employes will be downgraded because of the bumping or ripple effect of RIFs. Employes (with seniority and veterans preference) whose jobs are abolished can compete with colleagues for vacancies and, in some cases, bump down into lower grade jobs.

The number of specialized, high-grade professionals hit by layoffs will be greater than lower-level clerial employes who will find it easier to move into other jobs during RIF actions.

Defense -- which has 78,000 civilians here working for DOD itself, Army, Navy and Air Force -- does not anticipate any RIFs. But many people who were counting on shifting over the Pentagon could be disappointed. Defense does not plan any major buildup of civilian federal workers, although it will turn to more contracting out. DoD asked Congress for funds to rise to 930,000 civilian workers by the end of this fiscal year (Sept. 30) and to go up to 936,000 during the next fiscal year. As of March, DoD already had 928,000 civilian workers on the payroll.
