U.S. Postal Service will give annual cost-of-living adjustments (COLA) of about $700 next month to most of its $5,000 management employes, including more than 2,000 white-collar employes at its headquarters here.

The May COLA will be the same as the raise due 600,000 rank-and-file employes whose wages are set under union contract. Those employes get two COLA each year, in addition to regular annual pay raises.

Postmaster groups and the National Association of Postal Supervisors have been pushing for the management-level COLAs to help maintain salary differentials between rank-and-file employes -- clerks and carriers -- and supervisory, management and white-collar postal workers not covered by union contracts.

In addition to the May COLA, the supervisory and white-collar workers will also get the same dollar increase as rank-and-file employes this November, when the next inflation-catchup raise comes due.

Full cost-of-living adjustments will go to all non-union employes up through postal service grade 23, which has a salary range of approximately $27,000 to $38,000.

Employes in grades 24 ($28,000 to $40,300) and above will get only 75 percent of the COLA that goes to other supervisory workers and rank-and-file workers covered by union contract.

In addition to the 2,000 headquarters personnel who will get the raises, several thousand other supervisory-level people in post office regional and district offices here will get full or partial COLA, depending on their grade levels.
