CHICAGO — A seven-week strike has come to an end after a unanimous vote by the Local 150 construction union.

Several members of Local 150 had an in-person vote at noon Tuesday. A tentative agreement was reached and it ended the strike. It is unknown when several road projects may start up again.

The strike began on June 7 when about 300 heavy equipment operators, who are members of Local 150 and who work in Chicago area quarries went on strike claiming unfair labor practices against three companies that produce construction material.

The strike impacted the supply of asphalt and concrete which then slowed down or even put several area projects on hold.  

On Sunday, members voted down a deal which union representatives say wasn’t meeting the demands of the members.

In a joint statement Monday, in response to the vote, the companies in question expressed their disappointment with Sunday’s results, but said they were committed to servicing their customers and limiting disruptions to infrastructure projects to the best of their ability.  

A union spokesperson said the agreement means that every member working under it would see a 16.1% salary increase for the next three years. They also said there will be additional increases to members who are miners working underground, skilled heavy equipment mechanics and people who work second and third shift.
