ST. PAUL, Minn. (AP) -- Nurses have reached a tentative agreement on a new three-year contract with Children's Hospitals of Minnesota after union nurses had authorized their negotiating team to call for a strike.

The Minnesota Nurses Association says negotiating teams agreed on contract terms early Saturday after meeting for than 21 hours. The hospital approved an insurance plan that no longer forces nurses to pay more of the rate hikes than the hospital does, which was a sticking point in negotiations.

The company also agreed to provide the nurses with their largest wage increases in a decade, offering raises of 3%, 3% and 2.25% in the next three years.

Nurses voted Thursday to authorize a strike, which no longer applies. The vote to approve the contract is scheduled Thursday.

Contract talks began in March.
