A smaller portion of part-time workers eligible for employer-sponsored health insurance sign up for the coverage compared to full-time employees, according to a new study from ADP Inc., an employee benefits administration services company headquartered in Roseland, N.J.
The "2012 Study of Large Employer Health Benefits" found that 53 percent of part-time workers who are eligible for health insurance benefits elect coverage, compared to 77 percent of eligible full-time workers.
Among full-time workers at large employers, 88 percent are eligible to receive health benefits, while just 15 percent of part-time employees are eligible.
That could change in 2014 when a provision of the Affordable Care Act goes into effect requiring employers that offer health benefits to extend them to employees who work at least 30 hours a week.
The average employer included in the study contributed $7,225 a year in health premiums for each employee who enrolled in an employer-sponsored health plan for 2012.
Employers with at least 5,000 employees as a group pay 14 percent less for health insurance than employers with 1,000 to 2,499 employees. Workers and their employers share the benefit of lower premium costs equally, ADP says.
This study is based on 2012 employee data from a subset of ADP's health and welfare benefits clients of approximately 300 U.S.-based organizations. Each of the companies in the study employs 1,000 or more employees, including both full-time and part-time workers.
