The nation's unemployment rate jumped to 5.5 percent in May - the biggest monthly rise since 1986 - as nervous employers cut 49,000 jobs.

The latest snapshot of business conditions showed a deeply troubled economy, with dwindling job opportunities in a time of continuing hardship in the housing, credit and financial sectors.

With employers worried about a sharp slowdown and their own prospects, they clamped down on hiring in May, said Friday's report from the Labor Department. The unemployment rate soared from 5 percent in April to 5.5 percent in May. That was the biggest one-month jump in the rate since February 1986. The increase left the jobless rate at its highest since October 2004.
