Unsurprisingly, the main factor for most workers wanting a new job is compensation. Twenty percent of those looking for new jobs are motivated by a potential higher salary. More than 30 percent of those seeking new opportunities for higher pay say they took their current job for lower pay, but now believe they should be paid more.

This desire for higher wages isn't lost on administrators and leaders at companies. The survey spoke with employers who recognize they should raise salaries to be competitive, but two-thirds say they cannot afford to do so.

While pay was the number one reason people are trying to find new jobs, there were also other considerations.

One is equal pay for equal work. There is a wide divide between employer and employees' perception of this, with more than 80 percent of employers thinking they pay employees the same wage for the same work, regardless of gender. But this isn't the case for the employees, with around 50 percent of respondents believing otherwise.

One of the most prevalent non-financial reasons people want to leave their current job is feeling undervalued. Almost a quarter of respondents feel their employer didn't take the effort to retain them over the last year. This included the one-fifth of respondents who had benefits packages reduced last year, and employees who see their employers as focusing on workplace relationships rather than financial or tangible benefits.

Growth opportunities and learning new skills is another factor for employees looking for new jobs. Almost 40 percent of workers have concerns about not keeping up with skills needed to be successful. A similar amount don't think they could get a promotion with their current skillset. Training provided by companies falls into this category, and almost half of respondents would grade their company's training programs a "C." Around 18 percent would give their employer an "A."
