DAYTON, Ohio (AP) _ School and union officials agreed Friday night on a tentative settlement to end a 16-day teachers strike.

School board spokeswoman Jill Moberley, who announced the agreement, said no details were available.

Union and board negotiators resumed talks Thursday after a weeklong break. They pledged to talk until the strike was settled. They bargained most of Thursday and resumed talks 4:30 a.m. Friday.

Talks previously stalled over proposed salary increases, incentive bonuses and employee contributions to health insurance.

Classes weren't canceled, but the student absentee rate has been about 60 percent since the strike began March 25.

The ups and downs of the talks distressed some striking teachers.

''I feel disappointed,'' said teacher Pam Tyrrell. ''It's taking so long, and so many people's lives are on the line.''

Ms. Tyrrell said the teachers' spirits were lifted when both sides agreed to a marathon bargaining session.

Dayton teachers have a starting salary of $22,500. The teachers had been working under the terms of the old contract, which expired last year.
