Oct 1 (Reuters) - Boeing's ( BA ) largest union on

Tuesday urged the planemaker's new CEO Kelly Ortberg to get more

involved in resolving a strike by around 33,000 U.S. West Coast

workers, after their healthcare benefits were cut.

"It's time for the new CEO to truly engage at the

proposal-based level and to take the reins from his subordinates

who are fumbling critical decisions like this one," said Brian

Bryant, president of the International Association of Machinists

and Aerospace Workers which represents the striking workers.

"There is no reason the health benefits question could not

have been punted on to allow more time for negotiations at the

table," Bryant added in a statement.
