NEW YORK (AP) ― A new survey says salaried U.S. workers can expect another year of modest raises in 2012.

After increasing salaries by 2.6 percent this year and last year, companies are planning a 2.8 percent bump in 2012, benefits and human resources consultancy Towers Watson reported Monday.

That’s somewhat smaller than raises in the last decade. From 2000 to 2006, the year before the Great Recession began, salaries rose an average 3.9 percent for workers who were not executives.

And the modest bump may not help add much buying power for shoppers. In the 12 months through July, prices for consumers have risen 3.6 percent, according to the government’s latest calculations.

Salary increases have been small, even though many companies are sitting on huge cash stockpiles. They’re being conservative with permanent salary hikes because of uncertainty about the economy and memories of the deep cuts during the recession, said Laura Sejen of Towers Watson.

Because of worries about the economy, companies are trying to avoid “fixed costs,” such as permanent payroll increases, Sejen said. Hiring has also been tepid this year. More than 9 percent of the country’s workers, or 13.9 million people, are unemployed.
