If you happily get out of bed every morning for work, you're one of the lucky ones — not everyone is satisfied with their current job.
These people feel stuck for a variety of reasons, including low pay, irregular hours or the inability to move upward, says a report published by CareerBliss.
The company identified the unhappiest jobs based on more than 100,000 employee-generated reviews between February 2011 and January 2012.
The ratings are based on key factors such as work-life balance, one's relationship with their boss and co-workers, their work environment, job resources, compensation, growth opportunities, company culture, company reputation, daily tasks, and control over the work that they do daily.
