According to an annual salary survey published by staffing firm Randstad, a tight labor market is driving up salaries as firms compete to hire the best workers.

That was one of the findings in Randstad’s 2017 Salary Guides. The study predicted up to 3 percent raises across industries as the market settles. In turn, the lack of qualified, available workers has also left open positions empty.

“It's become a candidate-driven market again, and job seekers have more tools at their fingertips than ever to determine if they are getting paid what they're worth," Jim Link, Randstad North America’s chief HR officer, said in a press release.  

One of the resources job seekers have is Randstad’s survey, which can help in-demand candidates evaluate offers. According to the release, the guide assesses pay ranges in engineering, finance and accounting, human resources, information technology, life sciences, manufacturing and logistics and office and administration.
