President Bush is expected to issue an executive order this week raising the salaries of senior career and political executives between 18 and 25 percent next month. Some top executives will get raises of as much as $42,000 a year. It will be the first time civil service pay has cracked the $100,000 barrier.

Congressional salaries also will increase 25 percent next month, to $125,100.

A 4.1 percent pay raise for other federal workers -- including about 350,000 in the Washington area -- has been approved for January. The typical white-collar U.S. worker in Washington makes about $38,000 a year, according to the government. Retired federal workers, military retirees and people getting Social Security will get a 5.4 percent cost-of-living adjustment in January.

The executive raises are not official until the president approves them. They were negotiated a year ago by the White House, Office of Personnel Management and the Senior Executive Association. The association represents many of the 8,000 members of the Senior Executive Service. Most members of the executive service are in the Washington area.

Under the new pay schedule, Senior Executive Service level one in January would go to $87,000; level two would be $91,200; level three, $95,300; level four, $100,500; level five, $104,600; and level six will go to $108,300. The current top executive salary is $83,600.

Pay for those under the Executive Schedule will go up as follows: level one, $138,900; level two, $125,100; level three, $115,300; level four, $108,300 and level five, $101,300.

Under the approved federal pay raise, workers in grades 1 through 18 will get a 4.1 percent adjustment next month. The new minimum and maximum salaries are:

The open season for making changes in federal thrift savings plan accounts ends Jan. 31. I shortened the hunting season by almost two weeks in yesterday's item about the tax-deferred investment program open to federal workers and retirees. Starting next year, employees can invest -- without restrictions -- in any or all of the savings plan's options: the G-fund (treasury securities), the F-fund (bonds) and C-fund (stock market). Rates for the F and C funds will follow the performance of their respective markets. The G-fund rates are set each month. In 1987, the fund had an average annual rate of 9.08 percent. In 1988, it was 9.19 percent. In 1989, it was 9.01 percent. For 1990, the rate is 8.97 percent.
