"Regardless of what the government reports, Gallup's unemployment and underemployment measures show a sharp deterioration in job market conditions since mid-January," the firm said in a statement accompanying the release of the data.
Gallup also found that 10 percent of American workers have part-time positions despite wanting full-time work.
"The mid-February reading means the percentage of Americans who can only find part-time work remains close to its high since Gallup began measuring employment status in January 2010," the polling firm said.
President Obama has seen his approval ratings steadily rise — and those of his GOP opponents noticeably decrease — since a sunny jobs report in January. Although the White House cautioned then that emphasis should not be put on any single month's figures, Obama's reelection campaign and the Democratic National Committee both touted the numbers in online ad campaigns.
