Only 28% of US workers love their current job and would not leave for any reason; on the flip side, 14% do plan to leave their current job in the next 12 months, according to research by Yoh, a Philadelphia-based staffing firm. However, salary is a driver of turnover for those who would leave — whether in the next year or a longer timeframe.

Yoh’s research found that 14% of employed US adults believe they will need to look for a job in the next three years to get the raise they feel they deserve. In addition, 11% have been unsatisfied with recent raises and would consider another job because of it.

The research also found that 26% would leave their current job in the next 12 months only if they receive a higher salary and/or better benefits.

Opportunities to work on more exciting projects and get a new boss were factors in encouraging employees to move on, but pay is also a concern even in these cases. Only 7% of employed Americans would leave their current job for one with more exciting projects if the pay remained the same. In addition, only 6% would leave their current job to work for a new boss if they received the same pay.

This survey was conducted online by The Harris Poll on behalf of Yoh from Aug. 29 to Aug. 31 and included 1,175 employed adults.
