Interrupting family dinners with phone calls about products that people often don't need may lead some telemarketers to question the worthiness of their line of work.
More than 9% of telemarketers surveyed by PayScale said they thought their job made the world a worse place -- well above the industry wide average of less than 1%.
"Apart from door-to-door salespeople, telemarketers may be perceived as one of the most annoying sales professions," said Joel Garfinkle, career coach and author of "Getting Ahead: Three Steps to Take Your Career to the Next Level." "They enter your home -- via the telephone -- uninvited."
If you represent or sell a product that you believe actually has value for consumers, however, the job could become more meaningful, he said.
The American workplace is less dangerous than it was last year, but at these 10 jobs every day is a gamble.
