An advisory panel has recommended that the minimum wage for clerical and semitechnical employes in the District of Columbia be raised to $4.45 an hour, putting them $1.10 an hour over the federal minimum wage.

The D.C. Wage-Hour Board, a largely autonomous panel that functions within the city's Employment Services Department, will hold a public hearing on the proposal at 1 p.m. March 8 at the Martin Luther King Library.

By law, the District may set wage floors for various employe groups that are higher than those imposed by the federal law for the entire nation. Only employes of certain small businesses and, in some cases, juvenile workers, are exempt.

The most recent wage order, issued by the D.C. Wage-Hour Board last September, set the hourly minimum for retail employes at $3.50. Technically, the D.C. hourly minimum for clerical and semitechnical employes affected by the proposed new order is now $2.90, which was set in 1977, but that was superseded by the federal minimum wage when it rose beyond that level.

The new proposal would affect about 9,000 messengers, cashiers, tellers, practical nurses, nurses' aides, institutional attendants, day-care center aides and similar workers employed by physicians, hospitals, schools, banks, parking companies, messenger delivery firms, professional offices, associations and the like.
