Boeing announced Friday that it will eliminate 17,000 jobs—10% of its workforce—as it deals with deepening losses. Machinists are on strike against the company, which already was dealing with damaging safety and manufacturing problems.

Last month, 33,000 workers walked out of Boeing plants in Washington state after members of the machinists’ union overwhelmingly rejected a new contract. The work stoppage halted production of the company’s 767 and 777 planes, further cutting revenue, putting strain on its suppliers and customers.
