Each year I look forward to reading the list of the Most stressful jobs in America, which is compiled by CareerCast.com (I guess I like to see if I know anybody who works in a field on the list). When creating this list, CareerCast.com looks at 11 factors that can cause stress on the job, including work environment, job competitiveness, physical demands and opportunity for advancement. It then ranks 200 professions by how these factors influence the average workday.
