Over 33,000 Boeing workers who have been on strike for the past seven weeks are headed back to work after a Monday vote by union members who narrowly approved a new labor contract with the aerospace giant.

About 33,000 workers at the aerospace manufacturer had been on strike for nearly two months, having rejected two earlier contract offers.

The deal includes pay raises of 38% over four years, and ratification and productivity bonuses. Boeing refused to meet a demand to restore a company pension plan.
