According to a recent Gallup poll, 18% of American workers are worried about losing their job — down from a peak of 31% in 2009 in the wake of the Great Recession. American workers have good reason to feel secure. The economy has added jobs for the last 100 consecutive months, and the unemployment rate recently hit its lowest point since the 1960s.

Still, while the jobs picture in the United States is encouraging on a broad scale, on a more granular level, certain jobs are inherently less secure than others.

24/7 Wall St. reviewed unemployment rates by occupation from the Bureau of Labor Statistics to identify the occupations with the best and worst job security. The 32 jobs with the highest job security have unemployment rates below 1.0%, while the 32 jobs with the lowest job security have unemployment rates of at least 6.6%.

The jobs with the lowest job security tend to require little education. Many of these jobs are also projected to become less common in the future as automation will reduce hiring demand.

Meanwhile, the most secure jobs typically require at least some college, and often a doctoral or professional degree. Additionally, partially because the government never goes out of business, these jobs are far more likely to be in the public sector, either at the local, state, or federal level.
