Over four million people in the U.S. quit their jobs in December, according to figures released Tuesday by the United States Department of Labor.
That represents a decline of 200,000 from November, data showed.
Job openings rose slightly by 150,000 to reach 10.9 million in December, up from 10.7 million in November.
The market expectation was for 10.3 million jobs to open up.
In December, the number of hires decreased to 6.3 million.
The survey measures job vacancies by collecting data from employers about employment, job openings, hiring and separations.
