WASHINGTON, Sept 2 (Reuters) - U.S. employers likely continued to hire workers at a strong clip in August while steadily raising wages, signs of persistent labor market strength that could encourage the Federal Reserve to deliver a third 75 basis point interest rate hike this month.

The Labor Department's closely watched employment report on Friday would come a week after Fed Chair Jerome Powell warned Americans of a painful period of slow economic growth and possibly rising unemployment as the U.S. central bank aggressively tightens monetary policy to quell inflation.

The anticipated solid job growth last month would be further evidence the economy continues to expand even as gross domestic product contracted in the first half of the year. It is also a sign the Fed still needs to cool the labor market despite the front loading of rate hikes.

"If we're still talking about job growth of 300,000, and an unemployment rate of around three-and-a-half, or 3.6%, I think the Fed really thinks that the labor market can absorb more aggressive tightening," said Will Compernolle, a senior economist at FHN Financial in New York. "We're pretty far from any pain as far as the labor market is concerned."

Nonfarm payrolls likely increased by 300,000 jobs last month after surging 528,000 in July, according to a Reuters survey of economists. That would mark the 20th straight month of job growth. While that would be the smallest increase in 16 months, it would still be way above the pre-pandemic average.

Estimates for payrolls growth ranged from as low as 75,000 to as high 450,000. The unemployment rate was forecast unchanged at a pre-pandemic low of 3.5%.

Despite the uncertain economic outlook, demand for labor remains strong. There were 11.2 million job openings on the last day of July, with two job openings for every unemployed person.

First-time applications for unemployment benefits remain low and the Institute for Supply Management's measure of factory employment rebounded in August after three straight monthly declines. Comments from factories surveyed by ISM showed they "continued to hire at strong rates in August, with few indications of layoffs, hiring freezes or head-count reductions through attrition."

WORKER HOARDING

But the response rate to the Labor Department's establishment survey, from which the nonfarm payrolls count is derived, has historically tended to be low in August, resulting in initial job gains arriving below expectations.
