IT professionals looking for a higher salary should "arm themselves with third-party information so that they can be quantitative about what they're asking for rather than just emotional," said Silver.

"They should know that the pendulum has swung back in their favor a little," he said. "The market is tight and employers don't want to lose good people. So there is a chance for them to take advantage of that."

Even with strong corporate IT hiring, the overall economy is slowly bettering and businesses still harbor fiscal concerns, Silver added.

"The environment is changing," he said. "It's not great, but it's improving. [Employers] believe they're going to be hiring more people in the second half of the year. Not dramatically more, but they're feeling better [about the economy]."
