NEW YORK (AP) _ The New York City Opera has reached a settlement with the theatrical wardrobe union, averting a strike that threatened the opening of its season next week.

The agreement, reached Thursday, is subject to a ratification vote by the union on Sept. 18.

The Theatrical Wardrobe Union Local 764 voted unanimously last Wednesday to authorize a strike of the City Opera. The season opens Tuesday with a performance of Handel's ``Alcina.''

The four-year contract calls for a 3 percent retroactive increase to last November when the last pact expired, and 3 percent raises in each year of the contract. The wardrobe workers currently earn an average of $23 to $25 per hour.

Local 764 has 1,030 members union. It is affiliated with the International Alliance of Theatrical Stage Employees.
