Jason W. Speer, vice president and general manager, said that although high prices for energy and raw materials had temporarily made the firm hesitate, “we’ve been getting long-term commitments from our customers, and we have felt fairly comfortable.” He added: “I can easily see hiring two or more before the end of the year, if we have no more bumps.”

Economists who saw signs of lasting momentum said they did not believe a few hiccups in coming months would derail the recovery this time. “I do view this impending softness as a temporary response to the rise in oil prices,” said Ian Shepherdson, chief United States economist at the High Frequency Economics research firm, “not a fundamental reversal.”

Austan Goolsbee, the chairman of the president’s Council of Economic Advisers, said several signs pointed to continuing strength in hiring, including slower productivity gains after a fairly sharp run-up. After companies squeeze all they can out of their existing workers, they need to add more. “This is clearly the track you want to be on to plow your way,” Mr. Goolsbee said.

Average hourly earnings increased by 3 cents, to $22.95, and the average workweek was flat at 34.3 hours. Heather Boushey, senior economist at the liberal Center for American Progress, said she was concerned that neither wages nor hours were moving strongly upward, as would be expected if companies were wringing all they could out of their existing workers. “We’re not out of the woods,” she said. “As much as I think it would be such a relief to say, ‘Hey, this is the out-of-the-woods report.’ ”

Among job seekers, the least educated, African-Americans and teenagers continue to have the highest unemployment rates. For workers in the 55-and-over age group, the average duration of unemployment spiked to 53.6 weeks, compared with 39.4 weeks for those younger.

A weak area was government — local, state and federal — where the work force contracted by 24,000 jobs. Construction added 5,000 jobs, though mostly because of gains in heavy and civil engineering, probably helped by the remaining federal stimulus dollars devoted to infrastructure projects like highways. Most other segments of construction, including residential, shrank.

Temporary help, which has been strong, lost 2,300 jobs. Executives of two temporary services companies, Tig Gilliam, chief executive of the Adecco Group North America, and Jorge Perez, senior vice president of North America for Manpower, said companies that had relied on contract workers early in the recovery were now hiring.
