While all employers have specific criteria for potential job candidates, some companies across the country are only considering applicants who currently have jobs, CNN.com reported.

On some companies’ job postings, restrictions clearly state that an applicant “must be currently employed.”

“I don’t have hard numbers, but three out of the last four conversations I’ve had about openings, this requirement was brought up,” Rich Thompson, vice president of learning and performance for Adecco Group North America, the world’s largest staffing firm, told CNN.

Employers are avoiding the unemployed in a time where about 5.5 people are looking for work for every job available, according to recent data from the Labor Department.

“It’s our preference that they currently be employed,” a human resources representative for the People’s Place, a job recruiting website for telecommunications and engineering industries, told the Huffington Post. “We typically go after people that are happy where they are and then tell them about the opportunities here. We do get a lot of applications blindly from people who are currently unemployed–with the economy being what it is, we’ve had a lot of people contact us that don’t have the skill sets we want, so we try to minimize the amount of time we spent on that and try to rifle-shoot the folks we’re interested in.”

The hiring managers from the People’s Place are not alone in their beliefs, as various other companies across the country have similar postings.

But experts said these companies could ultimately benefit from new, previously unemployed hires due to a recently-passed tax break that exempts them from paying 6.2 percent of the new hire’s wages through the remainder of the year.

“In the current economy, where millions of people have lost their jobs through absolutely no fault of their own, I find it beyond unconscionable that any employer would not consider unemployed workers for job openings,” Judy Conti, federal advocacy coordinator for the National Employment Law Project told the Huffington Post. “Not only are these employers short-sighted in their search for the best qualified workers, but they are clearly not good corporate citizens of the communities in which they work.”

While there are no laws prohibiting the discrimination of unemployed applicants, some minority advocates believe the practice could be illegal if it had a “disparate impact” on minority groups.
