Waxad ku qortaa sii wadida cutubkan - intii lagu jiray shaqo joojintii xeebta galbeed 1934
, Bridges wuxuu ahaa hogaamiyaha Ururka Caalamiga ah ee Longshoremen's Association (ILA). Sanadkii 1937-kii, wuxuu noqday madaxweynaha Ururka Caalamiga ah ee Longshore iyo Warehouse Union (ILWU). Kaliya geedi socodka Bridges ee u dhaqaaqaya CIO iyo sameynta ILWU waxay ku filneyd in Bridges uu ku soo baxo bogga hore ee 19 Luulyo 1937 ee majaladda "TIME". Warbixinteeda daboolka ah, "CIO to Sea", "TIME" waxay xustay in, iyadoo guuldaradii ay ku dhacday Little Steel Strike, John L. Lewis, madaxa labadaba United Mine Workers iyo Congress of Industrial Organizations ayaa u jeestay ururada badaha si ay uga caawiyaan dhisida CIO-da weli cusub. Hoggaanka bilowga ah ee CIO waxaa ka mid ahaa: Philip Murray oo ka tirsan Guddiga Abaabulka Shaqaalaha Birta (SWOC); Sidney Hillman oo ka tirsan Shaqaalaha Dharka Amalgamated; Harvey Fremming oo ka tirsan Shirkadda Shidaalka, Ceelka Gaaska & Shaqaalaha Qodista; iyo Charles P. Howard oo ka tirsan Ururka Daabacaadda. Lewis wuxuu horey isugu soo ururiyay dhowr hogaamiye oo ka tirsan ururka shaqaalaha badda: Joseph Curran oo ka tirsan badmaaxiinta East Coast ee kacdoonka ka dhanka ah (Ururka Badda Qaranka; Kabtan E. T. Pinchin oo ka tirsan Masters, Mates &amp; Pilots of America; Vincent Malone oo ka tirsan dab-damiska badda, saliidaha, biyaha iyo ururka tirtirayaasha; iyo Madaxweyne Mervyn Rathborne oo ka tirsan Raadiyaha American Telegraphists. Sida laga soo xigtay "TIME", Lewish waxay rabtay Bridges, oo markaa wali ahaa madaxweynaha degmada xeebta Pacific ee ILA, si uu u hoggaamiyo gacanta badda ee CIO. "TIME" ayaa ku tilmaantay Bridges inuu yahay "ninka xun ee Pacific". Si kastaba ha noqotee, "TIME" waxay sidoo kale xustay "Taasi waa xaqiiqda in inkasta oo Harry Bridges uusan ahayn kacaan, malaayiin dad ah ayaa u maleynaya inuu yahay" waxayna u sheegtay xaqiiqdaas inay tahay dhibaato suurtagal ah oo ku saabsan Lewis iyo rabitaankiisa ah inuu soo jiito ururada ay hogaamiyaan shuuciyada. Cadowga Bridges (sidaas darteed dhibaatooyinka Lewis), "TIME" waxay ku tilmaantay daabacaha William Randolph Hearst inuu yahay kan ugu weyn. Bishii Luulyo 1939, Bridges wuxuu ahaa "Agaasimaha Xeebta Galbeed" ee CIO.
