(Reuters) -A union representing more than 3,200 striking Boeing ( BA ) workers said on Friday it had agreed to resume contract discussions with the U.S. planemaker next week.

Shares of Boeing ( BA ) rose about 1%.

The International Association of Machinists and Aerospace Workers represents members who assemble fighter jets and munitions at Boeing's ( BA ) facilities in the St. Louis area.

The announcement comes a day after the union filed an unfair labor practice charge with the National Labor Relations Board against Boeing ( BA ).
