College degrees notwithstanding, the jobs market is getting tougher in other ways than just finding a job. There's the quality of the job itself—a combination of pay, benefits, type of work and level of stress—as well as other factors such as hours and interaction with the public, that combine to make it a good job or a bad one. And don't forget the potential for job growth (or obsolescence). In CareerCast's 2018 Jobs Rated report, there are 20 new job titles that weren't evaluated last year, all from health care and technology fields including medicine, software and information security. And those three career paths alone are predicted to grow more than 30 percent each by 2026, according to the U.S. Bureau of Labor Statistics. Five of the report's 10 best jobs, says the report, are either based on technology or directly tied to it.

For every good technology-oriented job created, skilled-labor positions are suffering, according to Steve Antonoff, vice president of human resources at CalPortland, a 3,000-employee cement and concrete producer headquartered in Glendora, California and a member of the Society for Human Resource Management. In an interview with SHRM, Antonoff said, "Decent paying jobs for those with limited education are disappearing due to automation, computerization and other advancements. Turnover is high in service-related jobs, and labor is short in skilled trades. All of this is creating challenges for many HR teams trying to fill positions." The job market has changed drastically in the 30 years that CareerCast has been evaluating jobs, with some positions, even some requiring high levels of skills, threatened by market changes that no one could have predicted only a few years ago and other jobs multiplying like rabbits in fields that weren't even fields not that long ago. Tech has killed some highly skilled jobs, such as watch repairer—no longer included in the report; cellphones have caused many not to bother wearing a watch. Other jobs that are no longer evaluated in the report include printing press operator (superseded by the Internet) and automobile engine assembler (done in by robotics). And some jobs are disappearing thanks to the gig economy rather than technology, such as taxi driver—but in the end, the result is the same: decent-paying jobs that don't require high levels of education are vanishing. Here are the five best and five worst jobs out of the 220 evaluated by CareerCast. Rankings are based on four criteria: income, growth outlook, work environment and stress.
