US Boeing workers strike over pay

Members of the Machinists Union, mainly based in Seattle, downed tools after last minute negotiations failed.

Boeing says it has offered more than $34,000 (£17,000) per employee in pay and benefits.

Analysts say the stoppage cause further delays in the delivery of the new Dreamliner aircraft.

The union says with that with Boeing's record profits and its members going without a pay rise for the last four years, the offer is not good enough.

Dreamliner delays

The Machinists Union is Boeing's biggest labour group, and the company has said it will not try to assemble aircraft during the strike.

Analysts say that the stoppage could cost Boeing at least $100m each day in lost revenues - as well as delays in delivering the Dreamliner.
