Detroit ? Contract talks between the United Auto Workers and General Motors Corp. recessed Monday night, slowed so much by the complexity of retiree health care and other issues that a deal could be days away.

Talks were to resume today, GM spokeswoman Katie McBride said.

Both sides reported progress, but a person who was briefed on the talks said it’s taking a lot of time to reach agreement on details and large dollar amounts. The person requested anonymity because the talks are private.

McBride said talks recessed at 8 p.m. Monday after bargainers began meeting about 10 a.m.
