Executives don't necessarily agree. A separate survey of CFOs found 44 percent are not at all likely to hire a candidate with a history of job hopping because they want to avoid losing them in the future.

But workers and managers are close to agreeing on one thing: When asked the number of role changes in 10 years that constitute a job hopper, professionals said five and CFOs cited six. 

Other key findings from the research:

• Seventy-five percent of employees ages 18 to 34 view job hopping as beneficial, compared to 59 percent of workers ages 35 to 54 and 51 percent of those 55 and older.

• Workers with a college degree or higher see the most benefit in changing jobs every few years (67 percent).

• Company size matters: 51 percent of CFOs at companies with more than 1,000 employees said a history of frequent job changes isn't relevant if the candidate is the right fit.

• The biggest drawback of job hopping, cited by 46 percent of workers, is being perceived as a flight risk.

"While job hopping can have benefits, too many employment changes can raise red flags with hiring managers," said Paul McDonald, senior executive director for Robert Half. "Professionals should take time to weigh the pros and cons before making a career move."

Companies struggling with employee turnover need to make retention a priority. Added McDonald, "In today's candidate-short market, keeping key performers engaged should be top of mind for managers. Businesses worried about losing talent to the competition should focus on improving corporate culture and strive to be the type of company employees want to stay with long term."

Robert Half offers the following tips for professionals when considering a job change — and for managers to attract and retain workers:

For professionals:

• Assess your current situation. Consider what you would be leaving behind by changing jobs, including your compensation package and nonmonetary aspects such as a supportive manager or team.

• Ask for a second opinion. Consult with a trusted mentor or specialized recruiter who can help you decide whether changing jobs is the best option or not.

• Leave on good terms. Give ample notice and complete outstanding projects before your last day. You never know when you will cross paths with current colleagues or if you may decide to return to your present employer.

For managers:

• Make your company a great place to work. Promote your organization's reputation and values to attract candidates who have similar principles. Highlight advantages, such as a positive corporate culture and flexible scheduling options, that make employees feel respected and excited to come to work.

• Implement succession planning at all levels. Have career path discussions with top talent so they understand how they can advance at your company.

• Invest in employees' growth. Offering professional development opportunities can increase job satisfaction of existing staff and attract in-demand candidates.
