Among those who lost their coverage through Sodexo this year was Julie Pemberton, a cashier at Curry College, a liberal arts institution near Boston.
Pemberton puts in more than 40 hours a week during the academic year. She's paying over $200 a month more in premiums since she switched to a plan from the Massachusetts health insurance exchange.
"I'm actually looking for a new apartment because this is just draining any savings I have," said Pemberton. "I can't just keep paying and paying and paying."
UNITE HERE, a labor union trying to organize Sodexo workers, said the company's cutback was facilitated by what it calls a loophole in federal regulations carrying out the health law's requirement that larger employers offer coverage.
The Obama administration responds that the employer, not the health care law, is to blame.
French-owned Sodexo is a multinational service company with U.S. headquarters in Maryland. It operates many college cafeterias and also provides other campus services. In January, Sodexo reclassified some of its workers as part-time by averaging their hours over a 52-week calendar year. That affected about 5,000 of its 133,000 U.S. employees.
Sodexo said it was acting to align itself with the health care law, which requires that employers with 50 or more workers offer coverage to those averaging at least 30 hours per week, or face fines.
Company official Peterson said Thursday that for benefits purposes, the company will now credit campus employees during the summer break with the hours they would have worked during the academic year.
The UNITE HERE union says federal rules require colleges and universities to essentially do the same thing for their faculty employees. But those rules don't apply to contractor employees in cafeterias.
"There is nothing in there that says contract workers are protected," said union spokesman Ethan Snow.
At least one college that examined the issue agreed with the cafeteria workers. Earlham College in Richmond, Indiana, recently amended its contract with Sodexo to require that the employees be offered coverage.
"Sodexo's classification system was not consistent with the practices of other vendors, or with Earlham's policies," said Sena Landey, vice president for finance at the Quaker-founded liberal arts institution.
Landey said it looks like a slip-up on the part of federal regulators.
"I think it has to be an oversight," Landey said. "I just don't understand why you would benefit faculty and not those on the lower end of the pay scale. I don't see the logic in it."
