The International Association of Machinists and Aerospace Workers (IAM) reached seven tentative contract agreements with United Airlines for 30,000 workers. According to IAM, the five-year accords run through 2021 and call for approximately 30% pay increases over the term of the deal and $100 million in lump sum payments. The contract also includes a 25% hike in defined-benefit pension benefits, stops outsourcing of work currently performed by IAM members, and provides for insourcing of additional work.

Though current agreements were not amendable until December 31, 2016, IAM and United agreed last October to open existing contracts one year early and engage in expedited negotiations, which led to the tentative agreements.
