The 10 Unhappiest Jobs in America

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.

Here are the top 10 jobs that make workers' lives miserable.

1. Security Officer

Average salary: $29,641
Bliss Score: 3.510/5

Why: "People might think that the work environment security guards often face, such as working late hours alone at night, would be what contributes to unhappiness," Matt Miller, the chief technology officer at CareerBliss told Smith. "However, our data shows that growth opportunities and lack of rewards in this field is what affected the overall sentiment around this type of job. Work environment scored relatively high."

Description: Guard, patrol, or monitor premises to prevent theft, violence, or infractions of rules. The BLS projected the growth of these jobs to be 18 percent through 2020.

2. Registered Nurse

Average salary: $60,857
Bliss Score: 3.549/5

Why: "Nurses . . . have more issues with the culture of their workplaces, the people they work with and the person they work for," Golledge says.

Description: Provide and coordinate patient care, educate patients and the public about various health conditions. The BLS projected the growth of these jobs to be 26 percent through 2020.

3. Teacher

Average salary: $43,663
Bliss Score: 3.595/5

Why: CareerBliss' chief executive Heidi Golledge told Smith: "CareerBliss has found through our research that teachers appear to be quite happy with their work and their co-workers. However, the rewards for their work, lack of support and lack of opportunities to be promoted counteract many of the good parts of the job."

Description: Prepare students for future schooling and working by teaching them a variety of subjects. The BLS projected the growth of grade school teaching jobs to be 17 percent through 2020.

4. Sales Engineer

Average salary: $71,283
Bliss Score: 3.636/5

Why: Smith reports that these engineers don't appreciate the "lack of growth opportunities, company's culture, compensation and support."

Description: Sell complex scientific and technological products or services to businesses. They must have extensive knowledge of the products’ parts and functions and must understand the scientific processes that make these products work. The BLS projected the growth of these jobs to be 14 percent through 2020.

5. Product Manager

Average salary: $81,865
Bliss Score: 3.648/5

Why: Smith says that these workers "voiced unhappiness with the range of growth opportunities, compensation, company culture and support."

Description: A blog describes product managers as those who "conceive the idea; run with it for many months; ... gather, [develop], test, [go] through the painful exercise of bringing that product to market, and then support it until it is made obsolete."

6. Program Manager

Average salary: $94,371
Bliss Score: 3.655/5

Why: Jacquelyn Smith at Forbes reports that "the unhappiest aspects of [this] job are a lack of growth opportunities, the culture of the company they work for and the surrounding workplace support system."

7. Marketing Manager

Average salary: $64,437
