Oct 23 (Reuters) - A union representing over 3,200

striking workers at Boeing ( BA ) said on Thursday that its

members will vote on October 26 on an existing contract offer

from the company with minor modifications.

The International Association of Machinists and Aerospace

Workers represents members who assemble fighter jets and

munitions at Boeing's ( BA ) plants in the St. Louis area.

The union, in a memo to its members said, the offer came

without a recommendation from its bargaining committee.

Boeing ( BA ) made modifications to its existing contract that

give strikers more time before returning to work and remove the

provision allowing non-union workers to perform union tasks for

up to 30 days after the strike ends.

Boeing's ( BA ) defense workers have now been on a strike for

about 80 days.

The union has been pressing the planemaker for a

contract similar to the one it had reached with its Seattle-area

workers last year, which included higher retirement plan

contributions.

The workers struck work on August 4, after rejecting a

second offer from Boeing ( BA ). They also rejected another proposal

that included a 24% general wage increase over five years and a

$4,000 ratification bonus.

The members, however, voted 90% in favor of a four-year

contract proposal floated by the union that Boeing ( BA ) refused to

consider.
