Solidarity in action. 🀜

Thank you to Dane Garcia, President of IUOE Local 564, and the entire Executive Board for sending a letter of support to the Texas City Metal Trades Council and our Ashland members.

In his letter, President Garcia reminded us: "Your brothers and sisters across our Union stand shoulder to shoulder with you. Your fight is our fight."

That's what solidarity looks like. When one local stands up, we all stand up. Thank you, Dane and Local 564, for having our backs.

🚨 Major Win at Prime Healthcare 🚨

Local 399 members at 6 Prime hospitals were ready to strike in extreme heat this holiday weekend. Instead, we won a contract that restores seniority, lifts wages, and provides back-pay for workers.

"Our members stayed united and it made a difference," said Local 399 President & Business Manager Pat Kelly.

This is what solidarity looks like. πŸ’ͺ

Hear directly from Local 399 members about why they are ready to strike at 6 Prime Healthcare facilities in Chicago. Thanks to the Chicago Tribune for helping us get the word out.

Skilled maintenance workers at six Prime Healthcare hospitals in Illinois plan to go on strike July 2, with their union alleging that Prime has interfered with their right to organize and bargain collectively.

Check out our interview with journalist Christian Farr, who is covering the Prime Healthcare strike for NBC Chicago. There is still time for Prime Healthcare to do the right thing and avert this strike.
