The index, which tracks classified ads for jobs, remains at 19 for the second month, but has fallen from 29 a year ago, the report said.
In the first quarter, help ads declined in all nine regions the Conference Board tracks, the report said.
The largest declines were in New England, down 26.8 percent, the South Atlantic, down 20.5 percent, and the Pacific, down 19.8 percent, the report said.
"The economy is still weak and job losses will likely continue through the summer," said Ken Goldstein, labor economist at the Conference Board.
"The prolonged period of slow economic growth and no job growth is feeding a sense of frustration. This is why consumer confidence is at a 16-year low," he said.
