Most white-collar federal workers will be getting a 9.1 percent pay raise beginning in October. That is the amount President Carter recommended and it will go into effect automatically unless Congress vetoes the plan by Sept. 30. That isn't likely because a veto would mean an even larger raise, of around 13.5 percent, for U.S. workers.

There are several exceptions to the 9.1 percent amount. Workers in the very lowerst pay grades will get a larger increase, of around 13 percent. Employes in the top pay levels -- at the $50,115.50 level -- will not get any pay increase this year. [See chart].

Veterans Administration medial employes, Foreign Service personnel and congressional staffers are in line to get similar 9.1 percent pay raises. D.C. Government pay rates will be decided by Mayor Marion Barry, Blue-collar (wage board) employes, and U.S. Postal Service workers are not included in the pay raise. Washington area blue-collar employes will be getting pay adjustments -- to be announced -- sometime in October. CAPTION: Chart, Here are the pay scales scheduled to take effect in October for most white-collar (General Schedule) federal workers, including 300,000 in the Washington area. The 9.1 percent increase for most grades will go into effect automatically unless Congress vetoes President Carter's recommendations. In that case, U.S. workers would get a raise of around 13.5 percent, representing a full-catch-up with private industry. There are 18 pay grades in the GS scale, and 10 longevity steps for most of the grades. 1Employes earning less than $9,000 per year will get increases larger than 9.1 percent. Officials and executives at or above $50,112.50 will get no pay increase this year. By Richard Furno -- The Washington Post
