Three Boeing Machinists will run in the March 6 election to succeed District 751 President Tom Wroblewski, a union official said Thursday.

The election follows a bitter two-month struggle between the local lodge of the International Association of Machinists (IAM) and Boeing management that ended with a January vote narrowly approving a deal to build the 777X in Everett while freezing the traditional pensions of 33,000 union members.

That outcome has left the union split and considerably weakened. Wroblewski retired last month, citing serious health issues brought on by the stress of the high-pressure 777X standoff.

The nominees to succeed him are:

• Jon Holden, a union official who in internal meetings strongly opposed the Boeing contract offer.

• John Lopez Jr., a former president of the local C unit in Auburn, who spoke out publicly at rallies against the Boeing 777X offer.

• Roy Wilkinson, who works on IAM/Boeing joint programs, which support union members with health and safety resources, training and career advice.

The leading candidate appears to be Holden. He has been endorsed by key activists in the various local units of District 751, including Wilson Ferguson, who was the most prominent public voice of union members opposed to Boeing’s offer.

On a Facebook page outlining his platform, Holden states that his goal will be to create “a sense of unity and purpose … through education, town hall style meetings, (and) aggressive enforcement of our agreement.”

The vote is from 5 a.m. to 6 p.m. next Thursday at local union halls.
