Boeing workers in the US have voted to accept the aviation giant's latest pay offer, ending a damaging seven-week-long walkout. Under the new contract, they will get a 38% pay rise over the next four years.

Approval of the deal with 38 percent raises over four years is a key step toward recovery after Boeing suffered billions in losses from the work stoppages and safety problems.

The approved contract offer includes a 38% raise over the next four years, a ratification bonus of $12,000 and expanded 401(k) contributions.
