Many Americans are unhappy at work. According to new research conducted on behalf of Rasmussen College, almost one in five Americans say they are dissatisfied with their job, partially because they have no room to grow. In fact, more than half of the 2,000 U.S. adults surveyed say they don't have significant growth opportunities in their current positions.

"Having a clear career path from the very beginning is critical so you don't end up stuck in a job without the right skill set or lacking in advancement opportunities," said Tamryn Hennessy, vice president career services at Rasmussen College. "Surprisingly, only 24 percent of those surveyed say they feel they're doing what they set out to do. That number rises to 39 percent for those with a graduate or professional degree. That's why Rasmussen College wanted to create a tool that helps people discover their strengths and interests and lays out a career path that's perfect for them."

The survey also highlighted potential reasons for attrition in the workplace. Almost two-thirds of the adults surveyed said they have considered quitting their job. Of those, 51 percent say they have thought about leaving because they don't get paid enough. Other reasons include a lack of advancement opportunities (31 percent), being unfulfilled (26 percent), too stressful (24 percent) and not using their education or skills (21 percent).

The Rasmussen College Career Hub, which launched in April 2014, is a free online resource designed to help people find a career that aligns with their goals, education, skills and interests. As people navigate the different elements of the hub, they are asked a number of questions about their abilities, experience and personal preferences including working environment, hours, tasks and salary. From there, people will discover what industries appeal to them.

"We know starting a career or leaving a job and starting a new one can be a nerve-wracking experience," said Hennessy. "When you are able to combine your skill set and passion with an opportunity in a growing industry, you are well on your way to a satisfying career. More than half of our survey respondents also told us doing something they love is just an important as their salary."
