For the past couple years, many American workers have been putting in longer hours to help cover the productivity gap left by the massive layoffs that took place after the recession hit.

Now maybe they’ll be seeing some rewards for all that hard work — a new survey shows a lot of companies will be handing out bigger raises in 2013 than they have in recent years.

The 1,500 large and mid-sized employers recently surveyed by consulting firm Mercer said they plan to increase salaries by an average of 2.9 percent next year, up from the 2.7 percent seen in 2012 and 2011. Top performers may wind up with even more — those go-getters could receive a 4.5 percent bump in pay.

But the industry in which you work matters, too. Oil and gas companies, which are raking in historically high profits, will give out across-the-board raises averaging more than four percent, while education and healthcare workers will only see their paychecks rise by about 2.5 percent.
