By CHRISTOPHER S. RUGABERWASHINGTON (AP) â¿¿ U.S. employers likely kept hiring last month at a modest but steady pace, despite tense negotiations that pushed the economy to the brink of the fiscal cliff. Economists forecast that employers added 155,000 jobs in December, according to a survey by FactSet. That would be slightly higher than November's 148,000. The unemployment rate is projected to remain at 7.7 percent. Stable hiring would mean the job market held up during the talks between Congress and the White House over tax increases and spending cuts that were not resolved until the new year. A trio of encouraging reports Thursday on private hiring and layoffs suggested companies did not panic last month, although the Labor Department report will offer a more accurate measure of how businesses responded to the uncertainty in Washington. "Given that we have restraints, the labor market data do appear to be improving," said Dana Saporta, an economist at Credit Suisse. While Congress and the White House reached a deal this week that removed the threat of income tax increases on most Americans, they postponed the more difficult decisions on cutting spending. And the government must also increase its $16.4 trillion borrowing limit by around late February or risk defaulting on its debt. Congressional Republicans are pressing for deep spending cuts in return for any increase in the borrowing limit. President Barack Obama has repeatedly said he wants the issues kept separate. Depending on December's figure, hiring may finish the year slightly below its 2011 pace. Employers added 1.84 million jobs in 2011, the most in five years. In the first 11 months of 2012, employers added 1.67 million. Job gains would have to top 170,000 in December to push 2012 ahead of the previous year. Some economists do expect gains at that level or higher.
