WASHINGTON -- The top Republican in the House called for a freeze on government spending after new data showed the U.S. unemployment rate had hit a 25 year high last month.

U.S. officials vowed Friday to break the "destructive cycle of job loss" after the Labor Department reported he nation's unemployment rate bolted to 8.1 percent in February, the highest since late 1983, as cost-cutting employers slashed 651,000 jobs amid a deepening recession.

Both figures were worse than analysts expected and the Labor Department's report shows America's workers being clobbered by a wave of layoffs unlikely to ease in the coming months.

"There is no light at the end of the tunnel with these numbers," said Nigel Gault, economist at IHS Global Insight. "Job losses were everywhere and there's no hope for a turnaround any time soon."

Since the recession began in December 2007, just two months after the Dow Jones industrial average hit a record high of 14,000 and the unemployment rate stood at 4.7 percent, the economy has lost 4.4 million jobs, more than half of which occurred in the past four months.

Labor Secretary Hilda Solis said she was boosting by $3.5 billion the money available to states for education, training and re-employment.

But Rep. John Boehner, R-Ohio, said the unemployment figures is a sign of a worsening recession that demands better solutions from both parties. He urged President Obama to veto a $410 spending bill that he described as chocked full of wasteful, pork-barrel projects. The Senate postponed a vote on the bill until Monday amid the criticism.

The net loss of 651,000 jobs in February came after even deeper payroll reductions in the prior two months, according to revised figures released Friday. The economy lost 681,000 jobs in December and another 655,000 in January.

Employers are shrinking their work forces and turning to other ways to slash costs -- including trimming workers' hours, freezing wages or cutting pay -- because the recession has eaten into their sales and profits. Customers at home and abroad are cutting back as other countries cope with their own economic problems.

With employers showing no appetite to hire, the unemployment jumped to 8.1 percent from 7.6 percent in January. That was the highest since December 1983, when the jobless rate was 8.3 percent.

All told, the number of unemployed people climbed to 12.5 million. In addition, the number of people forced to work part time for "economic reasons" rose by a sharp 787,000 to 8.6 million. That's people who would like to work full time but whose hours were cut back or were unable to find full-time work.

If part-time, discouraged workers and others are factored in, the unemployment rate would have been 14.8 percent in February, the highest on record.

Meanwhile, the average work week in February stayed at 33.3 hours, matching the record low set in December.

Job losses were widespread last month.

Construction companies eliminated 104,000 jobs. Factories axed 168,000. Retailers cut nearly 40,000. Professional and business services got rid of 180,000, with 78,000 jobs lost at temporary-help agencies. Financial companies reduced payrolls by 44,000. Leisure and hospitality firms chopped 33,000 positions.

The few areas spared: education and health services, as well as government, which boosted employment last month.

Disappearing jobs and evaporating wealth from tanking home values, 401(k)s and other investments have forced consumers to retrench, driving companies to lay off workers. It's a vicious cycle in which all the economy's negative problems feed on each other, worsening the downward spiral.

A new wave of layoffs hit this week.

General Dynamics Corp. said Thursday it will lay off 1,200 workers due partly to plummeting sales of business and personal jets that forced it to cut production. Defense contractor Northrop Grumman Corp., and Tyco Electronics Ltd., which makes electronic components, undersea telecommunications systems and wireless equipment, also are trimming payrolls.

The country is getting bloodied by fallout from the housing, credit and financial crises-- the worst since the 1930s. And there's no easy fix for a quick turnaround, economists said.

President Obama is counting on a multipronged assault to lift the country out of recession: a $787 billion stimulus package of increased federal spending and tax cuts; a revamped, multibillion-dollar bailout program for the nation's troubled banks; and a $75 billion effort to stem home foreclosures.

Even in the best-case scenario that the relief efforts work and the recession ends later in 2009, the unemployment rate is expected to keep climbing, hitting 9 percent or higher this year. In fact, the Federal Reserve thinks the unemployment rate will stay elevated into 2011. Economists say the job market may not get back to normal -- meaning a 5 percent unemployment rate -- until 2013.

Businesses won't be inclined to ramp up hiring until they are sure any economic recovery has staying power.

The economy contracted at a staggering 6.2 percent in the final three months of 2008, the worst showing in a quarter-century, and it will probably continue to shrink during the first six months of this year.

Given Friday's grim figures, Gault predicted the economy would probably shrink in the first quarter at a pace of at least 6 percent.

Fed Chairman Ben Bernanke told Congress earlier this week that recent economic barometers "show little sign of improvement" and suggest that "labor market conditions may have worsened further in recent weeks."
