Employment experts say they believe companies are increasingly interested only in applicants who already have a job.
"I think it is more prevalent than it used to be," said Rich Thompson, vice president of learning and performance for Adecco Group North America, the world's largest staffing firm. "I don't have hard numbers, but three out of the last four conversations I've had about openings, this requirement was brought up."
Some job postings include restrictions such as "unemployed candidates will not be considered" or "must be currently employed." Those explicit limitations have occasionally been removed from listings when an employer or recruiter is questioned by the media though.
That's what happened with numerous listings for grocery store managers throughout the Southeast posted by a South Carolina recruiter, Latro Consulting.
After CNNMoney called seeking comments on the listings last week, the restriction against unemployed candidates being considered came down. Latro Consulting refused to comment when contacted.
