Oct 18 (Reuters) - A union representing striking

machinists at Boeing ( BA ) said on Friday it is "actively

engaged in indirect discussions" with the planemaker that are

being facilitated by Acting U.S. Labor Secretary Julie Su.

"We are fully committed to these talks. It is our

responsibility to attempt to reach a resolution," said the

International Association of Machinists and Aerospace Workers

Local 751 in a social media post.

Around 33,000 of Boeing's ( BA ) unionized West Coast workers, most

in Washington state, have been on strike since Sept. 13,

demanding a 40% wage increase spread over four years and halting

production of the planemaker's best-selling 737 MAX and its 767

and 777 widebodies.

The talks are the first sign of movement in the more

than one-month-old strike since Boeing ( BA ) on Oct. 8 withdrew its

latest offer that included a 30% wage increase over four years,

after talks also attended by federal mediators broke down.

Boeing ( BA ) subsequently filed an unfair labor practice charge

against the union.

Boeing ( BA ) declined immediate comment on Friday.

Last Friday, Boeing ( BA ) announced it would cut 17,000 jobs, or

10% of its global staff and take $5 billion in charges,

continuing a year of tumult for the company.

Boeing ( BA ) announced a window for up to $25 billion in stock and

debt offerings over the next three years on Tuesday, as well as

a $10-billion credit agreement.

On Monday, Su was in Seattle for her first in-person effort

to help reach a deal. A spokesperson for Su declined comment on

Friday.

In September, nearly 95% of the West Coast workers rejected

Boeing's ( BA ) contract offer of a 25% pay rise over four years,

prompting the strike.
