As President Donald Trump continues to come under fire for failing to deliver sufficient help to Puerto Rico in the aftermath of Hurricane Maria—which killed dozens and left millions without power and running water—nurses, doctors, engineers, and other workers affiliated with various unions including National Nurses United (NNU) and the AFL-CIO have teamed up to assist with relief and recovery efforts.\u0022As nurses whenever there\u0026#039;s a call and there\u0026#039;s an ask, we go.\u0022\u0026nbsp;—Cathy Kennedy, National Nurses United\u0022I put out the call for help, and who listened? The unions,\u0022 said Carmen Yulín Cruz, the mayor of San Juan, the Puerto Rican capital.\u0026nbsp;Workers representing more than 20 unions boarded a flight to San Juan late last week \u0022in response to the urgent need to get highly skilled workers to Puerto Rico to help people seeking medical and humanitarian assistance, as well as to help with the rebuilding effort,\u0022 according to the AFL-CIO\u0026#039;s\u0026nbsp;Kenneth Quinnell.\u0022The nurses, doctors, electricians, engineers, carpenters and truck drivers on the flight will engage in various efforts, including helping clear road blockages, caring for hospital patients, delivering emergency supplies, and restoring power and communications,\u0022 Quinnell added.\u0026nbsp;¡Sí se puede! Over 300 union volunteers in San Juan fired up and ready to help with #PuertoRicoRelief #UnionUnited pic.twitter.com/5hmwNj5z1o— AFL-CIO (@AFLCIO) October 4, 2017\u0022When our union sisters and brothers see a need in our national or international community, we don\u0026#039;t ask if we should act, we ask how,\u0022 said Sara Nelson, international president of the Association of Flight Attendants-CWA. \u0022We are united in lifting up our fellow Americans.\u0022NNU, for its part, sent a delegation of 50 volunteer registered nurses from throughout the U.S. to help provide urgent medical assistance to those in need.\u0022As nurses whenever there\u0026#039;s a call and there\u0026#039;s an ask, we go,\u0022 said NNU vice president Cathy Kennedy, RN. \u0022From the reports I\u0026#039;ve heard especially the elderly that have been without oxygen, without food or water, are at risk, everyone\u0026#039;s at risk but particularly the children and the elderly.\u0022In total, more than 300 union members are taking part in the joint response effort, which could be seen taking shape on social media over the weekend.\u0026nbsp;\u0022We use the word \u0026#039;solidarity\u0026#039; a lot in the labor movement. The idea that when we come together, we are stronger,\u0022 wrote Liz Shuler, secretary-treasurer of the AFL-CIO. \u0022On this relief mission, it was solidarity in the truest sense of the word. Working people united around a common purpose — to provide help for those in need.\u0022RNs visit the southern edge of #SanJuan municipality, where there\u0026#039;s been no contact w/FEMA or official relief.
