WASHINGTON (AP) — U.S. employers added 155,000 jobs in December, a steady gain that shows hiring held up during the tense negotiations to resolve the fiscal cliff.

The solid job growth wasn't enough to reduce the unemployment rate, which remained 7.8 percent last month, the Labor Department said Friday. The rate for November was revised up from an initially reported 7.7 percent.

Each January, the government updates the monthly unemployment rates for the previous five years. The rates for most months don't change.
